### FRACTIONS

**CCSS.MATH.CONTENT.4.NF.A.1**

Explain why a fraction *a*/*b* is equivalent to a fraction (*n* × *a*)/(*n* × *b*) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

- Better Dirt, Better Lives : Begin with playing the Fish Lake game. A video of the section on crop rotation may be used by schools that don’t have Fish Lake installed. Give a presentation (included) on crop rotation. Watch a video on “What is one-half” and end the lesson with a presentation (included) on whether one-half is fair.

After watching the video, students will login to “Aztech: The Story Begins” on a device with the website or application. Students will be faced with a fractions problem in Level 1 which uses a calendar to find the fraction of days students did homework. The game character points out that 15/31 may not be “all the time” but it is still more than half. Throughout the game, students will be presented with AzTech history.
- Using Visual Models To Compare Fractions – 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.

Students will learn that a fraction N/N =1 and be able to solve problems with fractions equal to 1 in various contexts, including number lines, time and pizza. This is the bilingual version of the lesson above that includes resources in English and Spanish – Fractions Equal to 1 (Bilingual English & Spanish).

### DIVISION

**CCSS.MATH.Content.4.NBT.B.6**– Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

- Build Your Own Division Problem – This lesson plan will build upon the introduction to division with 3-digit dividends from the “Dividing 3-Digit Dividends” lesson. Students will be able to continue practicing dividing 3-digit dividends by 1-digit divisors through a short review, activity where students build their own division problems, and game play.
- Fill in the Blank: 3 Digit Dividends – This lesson plan will have students reinforce the previously presented concept of long division of 3 digit dividends by 1 digit divisors (Dividing 3-Digit Dividends and Build Your Own Division Problem) through a short review, an animated video, a fill in the blank division word problem activity, and game play.
- Breaking down division with remainders – This lesson plan will explore how students interpret remainders in the context of a problem. They will learn how to divide and have a number leftover. Students will be using the concept of division and remainders.
- Learn 4 math facts at once with Google slides. Start 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.

### ESTIMATION

**CCSS.MATH.CONTENT.4.NBT.B.5** – Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.

**CCSS.MATH.CONTENT.4.OA.A.3** – Solve multistep word problems posed with whole numbers and having whole-number answers using the four operation … Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

- Using estimation in multiplying two-digit numbers – The lesson begins with a brief explanation of multiplying two digit numbers, followed by students solving 3-5 problems multiplying two-digit numbers.

### PROBLEM-SOLVING STRATEGIES

**CCSS.MATH.PRACTICE.MP4** Model with mathematics.**CCSS.MATH.PRACTICE.MP1** Make sense of problems and persevere in solving them.

- In Problem-solving Two Ways , students learn about and practice the two strategies of building a model and visualization. The lesson above has a companion lesson for English Learners. Problem-solving Two Ways (Bilingual English & Spanish) is the same lesson from above but provides the resources, videos and Google Slides, in English and Spanish.
- Problem-solving with Pigs teaches two more problem-solving strategies, using operations keywords and starting at the end to see what a problem is really asking. It is part of a cross-curricular lesson that includes learning about how pigs are raised.
