### Lesson plan

# Act it Out!

#### Learning Objectives

Students will be able to represent and solve addition word problems with drawings and through acting.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

#### Introduction

*(5 minutes)*

- Tell a quick addition story problem to your class. For example, "There are 4 cats and 4 dogs playing on the farm. How many tails are there altogether?"
- Ask your students how they could figure out the answer to this problem.
- Have students share details about this problem (such as "each animal has one tail" or "altogether means addition") that can help inform the strategy they can use to solve it.

#### Explicit Instruction/Teacher modeling

*(5 minutes)*

- Explain that your example is called a
**story problem**, which asks a question about numbers using a story. - Invite four student volunteers to the front of the room to act as the cats and four volunteers to act as the dogs. Have them freeze in action.
- Walk next to each of the volunteers and gently tap them on the head while counting aloud, encouraging the class to count along with you.
- When you finish counting, ask your students how you can double-check to make sure you got the right answer.
- Invite a student to double-check your work by recounting the volunteers.
- Record the problem on the board as a drawing and an equation, reminding your students how an equation works by relating each part to the corresponding piece in the story problem.

#### Guided Practice

*(10 minutes)*

- Explain that your class will now get to act out another story problem, which they'll solve independently.
- Tell another story problem. For example: "There are four cows grazing at the farm. How many eyes are there altogether?"
- Ask your students what they notice about this problem. How many eyes does each cow have?
- Invite volunteers to act out the scene and select a student to solve the problem. Model counting along aloud and keeping track as necessary.
- Pass out paper to your class, and encourage everyone to figure out the number of eyes total using drawings.
- Ask students to hold up their work and go over it as a class.
- Highlight how you could add using the groups of two (eyes) for each animal, using repeated addition. Explain why you would use groups of two to your students.
- Demonstrate how you could also write an equation for this problem:
**2 + 2 + 2 + 2 = 8**.

#### Independent working time

*(15 minutes)*

- Hand out a copy of the How Many Ears? worksheet to each student.
- Support students as needed to complete the worksheet.

#### Differentiation

**Support:**

- Provide students with math counters to use while completing the worksheet in order to visualize each problem.

**Enrichment:**

- Have students figure out how many eyes are in their family using drawings and writing an equation.

#### Assessment

*(5 minutes)*

- Assess your students’ understanding by collecting the worksheets and determining if students were able to correctly solve each problem using drawings.

#### Review and closing

*(5 minutes)*

- Go over the worksheet problems with the class and invite a few students to share their work.
- Highlight the strategies that students used to solve each problem and demonstrate how you could also use an equation to solve each problem.
