#### Learning Objectives

Students will understand the meaning of the equal sign. Students will be able to determine whether equations involving addition and subtraction are true or false.

#### Introduction

*(5 minutes)*

- Remind students the meaning of the
**less than**(smaller),**greater than**(bigger), and**equal to**(same) symbols in numerical sentences. Explain that the value of both sides of the number sentence must be correctly represented by the symbol. - Have your students read number sentences as they would read a sentence in a book. For example,
*1 + 1 = 2.*Explain that this is true because the value of both sides is the same. Tell your students that the example*1 + 1 > 2*is not true. - Tell your students that they will be working to find the right symbol to make sure the number sentences are true.

#### Explicit Instruction/Teacher modeling

*(5 minutes)*

- Review with students, through simple examples, numerical sentences that practice these symbols. Examples used might be:
*6 - 1 < 7, 6 - 1 > 4*and*6 - 1 = 5*.

#### Guided Practice

*(10 minutes)*

- Play Less Than or Greater Than: 1 to 20 with your students, explaining what true and false statements are.

#### Independent working time

*(10 minutes)*

- Pass out worksheets to your students based on skill level, and review the directions.
- Walk around the classroom, making sure that your students are following instructions and completing appropriate level worksheets.

#### Differentiation

**Enrichment:**Give students more challenging worksheets from the workbook, such as mixed addition and subtraction worksheets.**Support:**Give students worksheets that are easier to complete.

#### Assessment

*(5 minutes)*

- Direct your students to write an example of a number sentence that is true and a number sentence that is false in their math journals.
- Have them label these examples “true” and “false” and explain why the sentences are true or false.

#### Review and closing

*(5 minutes)*

- Quickly quiz students as a whole group with flash cards of true or false number sentences.
- Have students respond to true number sentences with a thumbs-ups or a thumbs-down.
