#### Learning Objectives

Students will be able to subtract 100 from multiples of 100.

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

#### Introduction

(5 minutes)
• Write the following numbers on the board: 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1,000.
• Ask students what these numbers have in common.
• Explain that all of these numbers are multiples of 100. This means that 100 two times is 200, three times is 300, etc.

Beginning

• Provide students with a video of someone counting by multiples of 100 up to 1,000 in their home language (L1).
• Guide students to point to and say the multiples of 100 up to 1,000 in English.

Intermediate

• Have students explain what multiple means to an elbow partner.
• Challenge students to list the multiples of 100.
