Learning Objectives

Students will be able to multiply by powers of 10 with exponents.

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

Introduction

(5 minutes)
Multiplying by Powers of 10Growing by Powers of Ten Chart
  • Write 10 x 1 = 10, 10 x 10 = 100, 10 x 100 = 1,000, and 1 0x 1,000 = 10,000 on the board. (Note: write each new equation above the previous one, making sure to align the equal signs)
  • Ask students to look for patterns and discuss with a partner.
  • Discuss patterns as a class (i.e., each equation is ten times greater than the one before; each equation has the same number of zeros in the product as in the two factors). Guide the discussion as needed.
  • Tell students that today they will be studying powers of ten (10 multiplied by itself a certain number of times).

Beginning

  • Allow students to use their home language (L1) or new language (L2) in their discussions.
  • Define the word pattern and show one in an everyday example (e.g., AABB pattern, etc.).
  • Ask students to restate the definition for "powers of ten" and provide an example.

Intermediate

  • Provide the following sentence starters for their discussions in their L1:
    • "I notice..."
    • "I wonder..."
    • "There are..."
  • Ask students to rephrase the definition for "powers of ten" and provide an example or two.
  • Write the academic language they can use throughout the lesson on the board as you introduce the language.
