Application Problem

Marshall puts 6 pictures on each of the 6 pages in his photo album. How many pictures does he put in the photo album in all?

Note: This problem is designed to review the Lesson 2 concept of applying the distributive property to relate multiplication by n + 1 to multiplication by n.

Concept Development

Part 1: Use number bonds to decompose and skip-count using units of 6.

Part 2: Use skip-counting sixes to solve multiplication and division problems. Example:
Write the equation 6 + 6. Then, draw a number bond to break apart the second six, showing how to solve using a make ten strategy.

Lesson 4 Homework

1. Use number bonds to help you skip-count by six by either making a ten or adding to the ones.

3. Count by six to fill in the blanks below.
6, ____, ____, ____, ___, ____

Complete the multiplication equation that represents
the final number in your count-by.
6 × ____ = ____

Complete the division equation that represents your count-by.
____ ÷ 6 = ____
