Introduction

(5 minutes)
Subtraction: Place Value BlocksInquiry Math Discussion Cards
  • 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.
