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.
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.
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, ____, ____, ____, ___, ____
