New York State Common Core Math Module 3, Grade 3, Lesson 17

Lesson 17 Problem Set

1 d. Use what you know to find the product of 7 × 16 or 8 sevens + 8 sevens.

Lesson 17 Homework

1. Write the products as fast as you can into the chart.
d. Explain how 7 × 6 = (5 × 6) + (2 × 6) is shown in the table.
e. Use what you know to find the product of 4 × 16 or 8 fours + 8 fours.
2. In the lesson, we found that n × n is the sum of the first n odd numbers. Use this pattern to find the value of n for each equation below. The first is done for you.
a. 1 + 3 + 5 = n × n
9 = 3 × 3
b. 1 + 3 + 5 + 7 = n × n
c. 1 + 3 + 5 + 7 + 9 + 11 = n × n
d. 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = n × n
e. 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = n × n
