Students will need a PC, Mac or Chromebook or tablet. Making Camp Premium, Making Camp Lakota and Making Dakota are all playable on any web browser on those devices. Spirit Lake: The Game, playable on Mac or Windows computers also teaches these same concepts or students can watch the videos from the game on any device with a browser.

## UNIT SUMMARY

This cross-curricular unit teaches solving word problems with multiplication and division with a variety of strategies and in contexts ranging from agriculture to traditional dwellings.

## Lessons

Lesson Multiplying to find perimeter of polygons

In this 45-minute lesson, students will learn how to compute perimeter of different polygons using multiplication and apply those skills in game-based practice problems. They will then learn about different Indigenous traditional dwellings. The lesson ends with students contributing to and solving problems that integrate the reading on dwellings and perimeter in an online assessment.

Multiplication word problems

In this 40-minute integrated lesson, students learn about responsibilities of children in traditional Dakota society and discuss their responsibilities today. They learn a problem-solving strategy that can be applied to a wide range of situations, including mathematics. Students play Spirit Lake: The Game or watch videos solving multiplication problems set in the context of a story based on Dakota culture.

Travois, multiplication and 2-step problems

In this 45-minute lesson, the students will develop an understanding of the meanings of the four operations of whole numbers through activities and problems involving real life scenarios from Indigenous history. Students use properties of operations to calculate products of whole numbers, using increasingly sophisticated strategies based on these properties to solve using the four operations problems involving single-digit factors. It includes educational videos, games and video presentations that can be used for reviews and daily practice.

Problem-solving with pigs: Start at the end

This 75-minute cross-curricular lesson includes activities and instruction in agricultural science and math. Students begin by watching a video and learning about pig farms. After making their own pig barn, they watch two short videos about solving math problems. This information is then applied to solve multiplication and division word problems during a presentation on math around the pig farm. Students end playing one of the Making Camp games to reinforce skills and knowledge.

Lesson. Problem-Solving Two ways

his 40-minute lesson assumes that students have some familiarity with multiplication of one-digit numbers and division with one-digit divisors. Students are introduced to the various means of problem solving in a brief presentation. They watch a video on visualization, then solve a problem that asks them to visualize. After watching a video on building a model, students build and/or draw their own model of a multiplication problem or property. Lesson concludes with game play to reinforce these problem-solving strategies and learn more. T

Learn 4 Math Facts at Once with Google Slides

This 60-minute lesson starts with a video as an ice breaker. Then, students read or listen to a presentation explaining how each math fact is actually four. Students complete an activity where they create their own math facts slides. A recommended video explains features of Google slides. Students complete the lesson playing Making Camp Dakota, solving word problems using division.

## Unit Summary

Students who have recently learned multiplication tables still need frequent review. These five lessons present multiplication review in a variety of lengths and formats; games, cross-curricular formats integrating Ojibwe history, flash cards, virtual manipulatives, slide presentations and video.

## Ojibwe History Integrated with Math + History = Making Camp

That’s Making Camp in a nutshell, um, equation. Each of these only takes about 10 minutes, teaches Ojibwe (Native American) history , multiplication or division. You can do these at the beginning or end of class as a warm-up, as an assignment for those students who finish early or combine all three for a 30-minute lesson.

### Lesson 1: Making Camp – 10-minute multiplication review and Ojibwe history

Do this lesson first. Students sign in to the Making Camp game, play through the introduction, play a memory game and get a virtual dog.

### Lesson 2 – 10 Minute Mini-Lesson: Rabbit Stew & Multiplication

Students learn about what foods the Ojibwe people ate and how their diet changed when they were forced on to the reservation. They play a multiplication tic-tac-toe to snare rabbits and spend the points earned in the game to outfit their wigwam.

### Lesson 3 – Trade for a wigwam

Not strictly multiplication review but this is where students trade in the points they have earned in the prior two lessons for items for their wigwam.Students will watch two brief videos, one on building a wigwam and one on trading between tribes.Clicking on each item gives information on how that item was used by the Ojibwe

## Lesson 4 – Multiplication Review and Red River Carts

Students watch a video on the importance of the Red River cart in expanding trade. The teacher presents (or students may read) a presentation discussing Red River carts followed by two related word problems. The 20-minute lesson concludes with students playing Making Camp Premium, reinforcing multiplication facts and the Ojibwe history lesson learned.

## Lesson 5- Multiplication Terms

Students watch a video on multiplication terms then review terms with flash cards. Students quiz each other with flash cards. This 40-minute lesson closes with practicing multiplication and division by playing Making Camp Premium.

By the end of Grade 3, know from memory all products of two one-digit numbers.

## Time

Each lesson will require 20-30 minutes. With the ten lessons, total time is approximately 5 hours spread over one to two weeks.

## Technology Required

Making Camp Premium plays in any browser and can also be downloaded on phones or tablets and played offline by students who have limited Internet access. The teacher will need a computer, for showing to students learning from home, and a projector if showing videos in the classroom. If the classroom does not have access to a projector, the videos can be skipped. Spirit Lake: The Game can be downloaded and played on Windows or Mac computers.

## Unit Summary

This 10-lesson unit teaches single-digit multiplication. Google slide presentations are provided within each lesson. Students are presented multiplication in a wide variety of formats, including, tables, number sentences, drawings, word problems and virtual manipulatives.

## Lessons 1-6: Multiplying one-digit numbers: 0 to 5

Students use visual drawings, manipulatives, and a number line to learn multiplication of one-digit numbers, coupled with their verbal explanations. Each lesson includes multiple assessments:

1. Students complete the multiplication tables – these can be shown with a projector (in class), on a screen, if teaching remotely, and on paper for students learning at home.
2. Students write their own number sentences using the multiplication learned each lesson.
3. Students complete the problems written by their classmates.
4. Optionally, students write word problems.
5. Optionally, student complete word problems written by their classmates.

At the end of lesson 5, students begin playing Making Camp Premium, which has teacher reports showing the number of multiplication problems attempted and answered correctly.

## Lessons 7-10: Multiplying one-digit numbers from 6 to 9

Students use visual drawings, manipulatives, and a number line to learn multiplication of one-digit numbers, coupled with their verbal explanations. Students play the Making Camp Premium game to reinforce learning. Those with access to a Mac or Windows computer can also play Spirit Lake. Each lesson will require 20-30 minutes.

• Students use visual drawings, manipulatives, and a number line to learn multiplication of one-digit numbers, coupled with their verbal explanations.
• Students will create number sentences independently and with a partner.
• Learning and memorizing multiplication patterns will improve later understanding of division.
• Determine the unknown whole number in a multiplication equation relating three whole numbers.
• Optional Brain Power activities have students write their own word problems.
• Students play games that reinforce memory and apply multiplication in word problems.

# Using Visual Models To Compare Fractions

## Standards

CCSS.MATH.CONTENT.4.NF.A.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2

CCSS.MATH.CONTENT.5.NF.A.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem.

## Technology Required

Students will need a Mac or Windows computer or an iPad to play the Fish Lake game. Alternatively, students can play Forgotten Trail on the web using Chromebooks or any computer with a web browser.

35-45 minutes

## Lesson Summary

Students play 2-3 levels of a game that teaches and assesses adding and comparing fractions with different numerators and denominators, with the context of a story from Ojibwe history. They create their own problems using visual models to compare fractions. Students discuss classmates’ problems. The lesson culminates with a video on visualization as a problem-solving strategy.

## Lesson

Students play the Fish Lake game through level 2. This requires installing the game on an iPad or a Mac or Windows computer. If only Chromebooks are available, students can play the Forgotten Trail Game instead. We do recommend Fish Lake if iPads are available. Although mathematics and social studies standards taught in both games overlap, the change from using Chromebooks in most lessons to a more console-level game can improve student engagement.

### Students create their own problems (10 minutes)

Use slides 1-4 of this Slides presentation to explain the assignment. Optionally, for students learning at home or for homework, it can be assigned to students in Google classroom or similar system.

### Discuss math problems students created (10 minutes)

Because students very often ask, “What do you mean?” or “Give me an example?” slides 5-11 of the presentation give an example.

## Assessment

This lesson includes three types of assessment. In the games, students are presented with math word problems that relate to the game narrative. Their answers are scored and data can be accessed for each student from the teacher reports. Students submit math problems they have written for teacher feedback. Also, teacher can use whole class discussion of student problems as a gauge for understanding or have students in pairs or small groups submit written discussion of their peers’ math problems.

# Cross-curricular Middle School Statistics Unit

Note: When we surveyed teachers from the 2021-22 academic year, the most requested addition to the site was to combine the lessons into units. This cross-curricular statistics unit has 12 lessons that total 14 hours of class time, although some assignments could be completed as homework. With the length of this unit, it could be taught as a complete summer school course, addressing primarily mathematics standards but also incorporating English language arts, Social Studies (predominantly Indigenous and Latino history and culture) and science.

variability in the data related to the question and accounts

Teachers begin the lesson with a Google slides presentation explaining the requirements for a statistical question. Students complete an assignment identifying whether or not a question qualifies as a statistical question. After class discussion, students complete a second assignment using a small data set shown on a map. In Part 3, students write and answer their own statistical questions using a data set provided, giving an explanation for their answers. Optionally, students can complete a more challenging assignment drawing conclusions from a graph and/or play a game and identify statistical questions.

### Lesson 2: Mean, median and mode (35 Minutes)

CCSS.MATH.CONTENT.6.SP.B.5 Summarize numerical data sets in relation to their context

Students play a game teaching basic statistics and history. Next, they are given a presentation with problems students solve finding mean, median, mode, range and outliers.

CCSS.MATH.CONTENT.6.SP.A.3 Recognize that a measure of center for a numerical data set summarizes all of its values with a single number.

This is a true STREAM lesson. Combining science, reading, art and mathematics. Students read a description of the pine forest ecosystem and life zones. They define any new words in their personal dictionary. Students then use information on plant life to identify life zones and locate these zones in terms of altitude. Students who complete the activity before the allotted class time play a game that teaches fractions and basic statistics.

### Lesson 6: Teaching Frequency Tables with Indigenous Communities’ Data (70 minutes)

CCSS.MATH.CONTENT.6.SP.B.4 Display numerical data in plots on a number line, including dot plots, histograms, and box plots.

CCSS.MATH.CONTENT.6.SP.B.5 Summarize numerical data sets in relation to their context

With a Google slides presentation, students are introduced to the concept of answering a question with data. A video is also provided for review. Using a data set of all tribal leaders in 2019, they are walked though an example of using Google Sheets to create frequency table and plots of data. Students then use the data set to create their own tables and plots. Students finish the lesson by playing a game where they learn about computing distributions in Mayan history.

### Lesson 7: Distributions and Mayan Trading (25 Minutes)

CCSS.MATH.CONTENT 7.SP.A.1 Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population.

The two videos here combine math and social studies, because, clearly, the Maya understood math. The concept of distributions is introduced in the context of trading, explaining why some objects are more valuable. Students play AzTech: The Story Begins, which reviews fractions and measures of central tendency. The lesson concludes with a question and another video on distributions.
(NOTE: Videos are available in Spanish and Englishfor English only lesson, click here. )

### Lesson 11: Probability and Fruits (45 Minutes)

CCSS.Math.Content.7.SP.C.5
Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.
CCSS.Math.Content.7.SP.C.6
Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.

The Google slides presentation begins with definitions of probability, impossibility and certainty. Students are then given an example of a basket with different types of fruits and the probability of each. Students each come to the front of the class and pull a piece of fruit from the basket, writing down the probability of their selecting the type they obtained. The class data is used to create a table and compare the obtained probabilities to actual distribution of fruit in the basket. The lesson closes with students creating their own probability question.

NOTE: This lesson plan requires a basket of fruit. You could use pictures of fruit printed out or drawn on paper instead but using actual fruit from your area might be more fun. If you’d rather, though, we do have a random fruit basket generator to use with this lesson.

### Lesson 12: Teaching Statistics in Classrooms with English Learners AND Native Speakers (90 minutes)

CCSS.MATH.CONTENT.6.SP.A.1 Recognize a statistical question as one that anticipates
variability in the data related to the question and accounts

75-90 minutes

## Summary

This lesson includes game-based instruction and data analysis. Data can be collected at home on students’ phones or using a computer. Google sheets is used to compute descriptive statistics to answer a statistical question. Lab instructions, Sheet templates and a sample answer are included. You can modify this in an infinite number of ways to compare any two groups on any numeric variable.

## Lesson

NOTE: This lesson assumes students understand:

### Discuss the definition of a statistical question.

If students have not completed the lesson, “What is a statistical question?” , you can complete that first. It takes about two hours.

If you are REALLY short on time, or if you are just reviewing the concept you have previously taught, you can just use the first 12 slides of this presentation on What is a Statistical Question?” to give the basic definition and a few examples.

### Class Discussion of Research Question

#### Pose a research question, for example, “Do different Spanish and English speakers differ in their interests, as determined by what they post on Instagram?” Of course, you can easily change the language if you have speakers of other languages in your class.

Next, you need a hypothesis, for example, “Spanish-speakers are more likely to post pictures of food than English speakers” or “English accounts will have more pictures of themselves than Spanish accounts”.

In selecting a hypothesis, you can discuss distribution and probability. If almost no one takes pictures of giraffes then the probability of finding enough giraffe pictures to compare is low. (Be prepared for your students to suggest the hashtag #giraffesofinstagram).

### Statistics Lab Assignment : Social Media Analytics

In this assignment, each group of students will collect and analyze social media data from 10 accounts of Spanish speakers and 10 accounts of English speakers. After individual assignments are submitted, data will be combined into a single class data set and the analyses re-computed for the combined data set.

#### Assign Groups

After you have agreed on one research question, put your class in groups of 4 or 5 students. Ideally, each group would have at least one Spanish speaker and at least one native English speaker. Ask students to raise their hands if they have an Instagram account. Try to put at least one student with an account in each group. Groups can also include students learning from home.

#### Share lab documents with students to collect, enter and analyze data

The spreadsheet for entering data can be found here. This is a Google sheet but it can also be downloaded and saved as an Excel file if you prefer.

#### Optional: Provide students starting links for accounts

To help students find accounts, you can include these links in your Google classroom or other classroom management system, or any list of accounts

You can find 50 inspirational accounts in Spanish here ( https://metricool.com/es/50-cuentas-de-instagram-ordenadas-por-tematica-para-inspirarte/ )

and 20 inspirational accounts in English here – ( https://wealthygorilla.com/top-20-motivational-instagram-accounts/ )

## Class discussion

Discuss the idea of variation within the accounts. Discuss the idea of variation across the groups. Did the different groups in your class find the exact same results?

Discuss variation in samples. What could have explained the different results? Did some groups have accounts that were all celebrities, all friends, all male?

## Play a game

Play Disaster Deduction Detectives (available June, 2022) to learn how to compute the median in datasets with odd or even numbers of data.

### Statistics Lab Assignment 2: Social Media Analytics with Larger Sample

In the second lab exercise (instructions found here) , students combine the data from all groups, and compute descriptive statistics again. They compare their group’s results with the whole class result and discuss possible explanations.

## Assessment

Three types of assessment are included. Group assessments are the two lab assignments submitted by students – since each student in the group has the same data he/ she will have the same result. Optionally, teachers may elect to have students submit their labs individually. Individual assessment is included within the DDD game where students must identify a statistical question, compute mean, median and quartiles. Whole class assessment occurs during the two discussion session.

There is a solution using algebra, with cross-multiplication and an explanation of why cross-multiplication works. There is also an explanation using equivalent fractions. If you are teaching an algebra class, use the first explanation and delete the second. For a more basic math class, delete the first explanation and just use equivalent fractions. Also includes a baking activity, not required but highly recommended.

NOTE: While we create most lessons on the Growing Math site ourselves, we do include links to other lessons that are exemplary in their cross-curricular, standards-based design. This lesson is one of two “lessons we love” from Discover Dairy. The entire 14-page guide with two lessons can be downloaded here, including reading passages, lab assignments and answer keys.

You can also go to the Discover Dairy site, which requires a free registration and login to download individual parts of the lesson and see the other lessons they have available.

### Class Discussion on Life Cycle

Using the discussion questions on page 4 of the complete lesson plan, discuss the dairy cow life cycle with students based on their knowledge from the reading.

### Lab Exercise #2 Feeding a Dairy Cow

Each student or group will need a scale or measuring cup and the following:

• 1 cup spinach
• Baby or whole carrots
• 1 cheese stick
• One 12 oz. cup of orange juice

Distribute the materials needed and the lab assignment (pages 11 and 12 of the complete lesson plan or you can link directly to those here, if you want to assign in Google classroom or other management system. Note that link includes both labs 1 and 2.) Lab explanation from page 5 of the complete lesson plan.

Teachers should explain that a healthy, well-cared-for cow will give more milk. The way farmers care for their cows and how they feed them has helped to increase the amount of milk cows give over the past 50 years.  Just like our diets, a cow’s diet must be balanced based on her stage of life. For instance, a baby calf requires higher energy foods to fuel her rapid growth.  A cow that has just given birth requires higher levels of certain nutrients to replenish her body. Farmers must adjust rations to accommodate those needs.  Farmers work closely with an animal nutritionist and use a variety of feed products to balance cows’ diets to meet their precise nutrient needs using a variety of feed products.  Farmers use a large feeding scale to make sure each cow gets the right amount of each feed. Those feeds are blended together to provide a balanced diet called a Total Mixed Ration (TMR). During the lab, students should use the carrots, celery, cheese and orange juice to balance a diet to meet the required nutrients listed on the lab worksheet. They should use a weight scale to measure the right amount of each feed. If they don’t have a weight scale, they can use measuring cups to determine the amount. Complete the ratios in the worksheet.

The lesson concludes with students watching videos that guide them through deciding on a long-term purchase using a spreadsheet.

## LESSON

### Introduction to budgeting discussion

Use this presentation to lead a class discussion on what budgeting is and why it is important.

During or after the presentation, ask these questions

1. Why is a budget important?
2. Name a short-goal.
3. Name a long-term goal.
4. What are 3 things on which you need to spend money?
5. Name 3 things on which you want to spend money.

### Project: Complete a personal budget

Introduce the personal budget project using this slides presentation that explains the purpose of the project and gives an example of a completed budget.

Assign the budget worksheet to students. This sheet can be opened and completed in Google Docs or downloaded and completed as a Word file. If students prefer, they can create a table in Sheets or Excel.

### Project: How Good is Your Budget?

NOTE: This activity is part of the Applied Digital Skills curriculum through Google for Education. You do NOT need to create a classroom in the Applied Digital Skills program to complete this lesson. The only activity that requires sign-in is submitting a quiz at the end, which is really just an evaluation of how well the student liked the lesson.

In the previous activity, students completed a budget. In this activity, students complete the research a long-term purchase using a spreadsheet. Although the videos are done by Google and use Google sheets, the steps in creating and duplicating a formula work identically in Microsoft Excel. The video examples use selecting a cell phone and phone plan but students can use any other expense that interests them, including renting an apartment or buying a car. Teachers can copy and paste the instructions below into their Google classroom.

#### Instructions to Students

1. Watch the Google for Education videos that you will find here on researching a long-term purchase.

2. Create a spreadsheet following the instructions in the videos. You can follow the video example of selecting a cell phone or use another long-term purchase, such as a car.

4. Submit a document in Word or Google doc explaining which option you picked and why.

ASSESSMENT:

Students will participate in a class discussion and complete the two budget worksheets for teacher review.

Differentiation:

You may wish for students to play the Crossroads: New Decisions game budgeting module.

IMPORTANT NOTE TO TEACHERS: As this game was developed for youth in high-risk situations it includes game levels on making a safety plan, the Adverse Childhood Events Scale and other topics not normally covered in the classroom. It would be most appropriate for students in a therapeutic setting or in a life skills class where topics such as abuse are discussed.
