Summary
This lesson includes game-based instruction and assessment.
Students register with a username and password, then play the game, in English or Spanish. You can have students register and select their own, or provide usernames and passwords you wish them to use, for example, an existing school login.
Each math problem has an EXPLAIN button that students can click to get an explanation of how to solve the problem. Some also have a hint, which is a short suggestion of how to go about solving it. For example, “Subtract the number of days you did not have homework, from the total number of days. Give the answer as a fraction of the total.”
We recommend encouraging students to read the EXPLAIN and any HINT buttons before asking the teacher for help.
4. If students miss a problem twice in a row, they are routed to a LEARN MORE page and need to select an option, which may be a video, web page with voice over or matching terms, to learn more.
Assessment
Students get immediate feedback on right or wrong answers. Assuming students are playing online, results of in-game math challenges are recorded to a database which teachers can access. Access to reports can be found here.

NOTE: Although the examples in this assignment primarily use scientific notation, it could be easily modified to include any area of mathematics above the fourth-grade level.
TIME
120 minutes – including time to play game and create problems and activities.
TECHNOLOGY REQUIRED
A projector and computer in class or a computer, phone or tablet at home is required to watch the videos, see the Google slides and play the Making Camp Lakota game. It is not required but strongly recommended that students have access to Google apps or Office 365 to edit and store their notes.
LESSON SUMMARY
This is the second in a multi-lesson unit designed to assess student mathematics proficiency by playing games that teach about Indigenous cultures that have embedded math problems. It also requires students to create their own math activities and math problems.
LESSON
Introduce today’s lesson with slide presentation
This lesson assumes your class did the previous lesson, Math Assessment and Ojibwe culture, where they were introduced to the purposed of the unit and (recommended) created a Google slides or doc file where they are taking notes.
The Making Camp Lakota game teaches Lakota culture and division with single-digit divisors. Even older students should enjoy the game play aspects and the videos on Lakota history and culture. Middle school students should breeze through the math problems. These are recorded in the database for teachers to review student progress.
Each game in the series in this unit is gradually more difficult math problems.
Students create their own, grade-level math problems
The slides presentation instructs students, for each math activity, to create an example that could be used at their grade level. Most of the examples in this presentation are using scientific notation, but students should be instructed that they can use any math problems beyond simple division. That could be fractions, decimals or even long-division. Teachers can modify the slides at the end of the presentation to require a specific topic, for example, adding fractions without a common denominator.
ASSESSMENT
Making Camp Lakota teacher reports are available for assessing student answers in Data and Reports. Students also write their own problems and answers that the teacher can use for assessing abilities at application and creation levels of Bloom’s taxonomy.
This lesson is appropriate for students whose math is from fourth- through eighth-grade level. The mathematics in the game is at the fourth-grade level but student assignments can be as simple as long division or as complex as multi-step equations with negative exponents.

Lesson Summary
This is an augmentation of a lesson from the Library of Congress uses a primary source – the Huexotzinco Codex – as a basis for document analysis, inquiry and applied mathematics. Students analyze pages documenting tribute paid to Spanish administrators, compute the tribute paid, read a one-page overview of the codex and analyze the codex. A presentation is given on connections between Aztec, Mayan and contemporary methods. Students begin or end classes playing a game that includes Mayan history and middle school mathematics.
Lesson
First, some background for the teacher. The Huexotzinco Codex was part of the evidence in a case brought by the Nahuas, Indigenous people of what is now Mexico, against the Spanish administrators, alleging excessive taxation (tribute). This case was won by the Nahuas. In this lesson, students do not learn the full story until the third or fourth class period.
NOTE TO THE TEACHER: Allow at least 30 minutes before using this lesson the first time, to read through the Library of Congress lesson, download and print out documents for students.
Play a game
Have students sign in and begin the game, AzTech: Meet the Maya. Students should play for about 15 minutes.
Computation – How much was the tribute?
Continue with the second part of Library of Congress lesson, “The Huexotzinco Codex”, and have students complete Activity 2, Computation. After students have completed one tribute sheet and corrected their answers, use this slide presentation to show the connection between the Aztec and Maya codices and our modern system of numbers and graphs. Optionally, have students complete one or two more tribute sheets from the linked lesson. This should take one to two class periods.
Play a Game
At the beginning of class, have students continue the AzTech: Meet the Maya game. Students should play for 15-20 minutes by which time some of the students should have reached the codex activity and explanation in the game.
Four types of assessments are included; observation of student understanding of historical document analysis in the class discussion, student self-corrected math computation, student written assignments (analysis sheet, observations and scenario outlines) and the math problems in the AzTech game which are scored automatically with data available in teacher reports.
Differentiated instruction (optional)
Advanced Students who complete their assignments early can continue with the AzTech: Meet the Maya game. If they complete this game, they can choose to play AzTech: The Story Begins or AzTech: Empiric Empire.
English learners can play the AzTech : Meet the Maya and AzTech: The Beginning games in English or Spanish.

Technology
Students will need a Chromebook, Windows or Mac computer to play the game. Stories can be read on a computer or tablet or printed out.
Time Required
75 -105 minutes.
Summary
This lesson begins with a game teaching statistics, with a level assessing weights of salmon. Next, students read stories about salmon from the Pacific Northwest tribal communities. The lesson ends with a game outdoors or in the gym where students ‘catch’ salmon and learn the impact of overfishing. Optional activity includes creative writing or artwork to accompany the salmon stories.
Lesson
Play a Game (25 minutes)
Play Disaster Deduction Detectives through Level 4 where players compute mean weights of fish caught with and without an outlier. Earlier levels discuss median and statistical questions.
Fish catching game in Disaster Deduction Detectives
Read Salmon Stories (35 minutes)
This 35-page booklet of salmon stories comes from a collaborative effort of the tribal communities of the Pacific Northwest, Northwest Indian Fisheries Commission and Seattle Aquarium. In addition to four stories about salmon, traditional games featuring salmon are described. You can print the booklet or copy the link and assign it in your Google classroom or other online system.
Depending on your available class time and their reading level, you may wish to just assign one or two stories or the whole booklet.
Physical Education and Math – Play the Salmon Catcher Game (15 minutes)
This game is explained on page 30 of the Teacher’s Guide and on page 24 of the Salmon Stories booklet. A group of 4 or 5 students must catch a classmate (a salmon) by forming a net around it by holding hands. Play with lots of salmon and one ‘net’ and then with lots of ‘nets’ and few salmon. After the game, discuss how having too many fishers for the number of fish makes it difficult for each group to get enough salmon for a feast.
Assessment
Students responses to the questions in the Disaster Deduction Detectives game on statistical questions, creating and interpreting dot plots, median and mean with and without an outlier are all scored automatically and can be found in the teacher reports.
Differentiated Instruction
Optional: Creative Writing OR Art and Social Studies (30 minutes)
The Salmon Stories booklet has minimal illustrations. Allow students 30 minutes to create an illustration for one of the stories. For students who would prefer to write a story instead, allow them to select one of the topics suggested in the booklet, for example, on page 23 of the student booklet (page 29 in the Teacher’s Guide) students are asked to imagine a discussion between a salmon and the forest.
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.

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.

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.
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).
#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
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
Scene in the Disaster Deduction Detectives Academy
Play Disaster Deduction Detectives 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.
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. Of course, your average teacher could do this but your average teacher is also short of time.

📃Summary
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: Meet the Maya, which teaches measures of central tendency. The lesson concludes with a question and another video on distributions.
📚Lesson Plan
1. Watch video – Mayan Trading (1:57)
Also available in Spanish! – El Comercio Maya (1:58)
El Comercio Maya
The Mayan trading video is based on an idea from one of my favorite history teachers, who says that history is more than just names and dates but also how people lived, what they used, what they did. It also has a bar chart of the relative value of objects. It explains that the Maya traded less common items for more common ones and that items that were more difficult to obtain were more valuable.
José tried to trade a banana for a quetzal feather and a villager threw a spear at him. Why would the villager do that? Explain using math. Extra points if you can discuss distributions in your explanation.
José ofreció intercambiar un plátano por una pluma de quetzal y un aldeano le lanzó una lanza. ¿Por qué haría eso? Explica usando la matemática. Puntos extra si puedes hablar de distribuciones en tu explicación.

📃 Summary
This cross-curricular lesson is from Discover Dairy. Students read a passage on the life cycle of dairy cows. A guided class discussion answers questions on the life cycle. The lesson concludes with a challenging lab in which students create a healthy cow diet.
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.
Read a passage on the life cycle of a dairy cow
You’ll find this on page 14 of the handout linked above or download both reading assignments here (it’s only two pages) or copy the link to assign in your Google classroom to read on line.
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.
Review and Summarize Dairy Cow Life Cycle: What We’ve Learned
Review questions and summary can be found on pages 5 and 6 of the complete lesson plan.
ASSESSMENT
This lesson includes three types of assessment – the initial class discussion gives an estimate of the general class understanding of the dairy cow life cycle. The lab provides individual student data on mastery of both the science and math concepts. The concluding review questions can be poised to the whole class or given to students as a quiz.
