Subject: Math

Lesson Length: 30 - 45 mins

Topic: Numbers and Operations in Base Ten; Place Value in Multiplication

Standards / Framework:

Brief Description: Students will explain the pattern of the number of zeros of the product when multiplying by powers of 10. Students will recognize that powers of 10 are represented as 10 with an exponent.

Know Before You Start: This can be used as an introductory lesson for multiplying by powers of 10.

Hook:

• Read and discuss the sample comic.
• As each number is multiplied, what pattern do they notice?
• Discuss what powers of 10 are and how they are expressed with exponents.

Activity:

• Have students choose a number between 1 and 9 and multiply that number by 4 powers of 10 (101, 102, 103, 104).

• Remind students that they can find the product by adding the same number of zeros as the power of ten, e.g., 14 x 102  can be solved by adding two zeros to the number they are multiplying by.

• Have students compare their products with a partner.

• Using the sample comic as a guide, have students create a six-panel comic showing a number of their choosing multiplied by 5 powers of 10, one in each frame (101, 102, 103, 104, 105).
• Have students explain how the pattern of zeros works in the sixth panel.

Closure:

• Discuss how many zeros would be required for 1010 based on the way the pattern of zeros works.
• Display completed comics in a gallery walk or have students share their comics in small groups.

Differentiation:

• Allow students to use the speech-to-text feature.

• Allow students to use the voiceover feature to read their comics aloud.
• Provide sentence frames as needed.

• Provide manipulatives and visuals as needed.

Resources:

• Comic to print or display: Comic.
