What exactly does the number 97 mean? How about 454? In this lesson, students explore how two-digit numbers are made up of tens and ones. Then they use this understanding to subtract numbers within 1000.

#### Learning Objectives

Students will be able to subtract three-digit numbers using place value blocks.

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

#### Introduction

(5 minutes)
• Show students the place value blocks.
• Say, “These blocks show 100, 10, and 1. We can use these blocks to represent how many hundreds, tens, and ones we have.”

Beginning

• Provide students with visuals of the place value blocks to paste in their math journals.
• Have students write the corresponding value next to the visuals and orally share them with a partner in English or their home language (L1).

Intermediate

• Have students turn and talk to a partner, explaining place value blocks in their own words.
• Ask students to share how place value blocks can help us solve math problems.
