Learning Objectives
Students will be able to multiply by powers of 10 with exponents.
Introduction
(5 minutes)- 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.
