Eureka Math Grade 2 Module 7 Lesson 11 Problem Set Answer Key

Question 1.
Count up using the arrow way to complete each number sentence. Then, use your coins to show your answers are correct.

a. 45¢ + ________ = 100¢

Explanation:
45¢ +      = 100¢
100 – 45 = 55.
To make 55¢ using coins.
First we add nickel 5¢ to 45¢
45¢ + 5¢ = 50¢
Next we add 50¢ to 50¢ to make it 100¢.
Now to make 50¢ we add 2 quarter
25¢+25¢ = 50¢
First add 1 quarter to 50¢
50¢+ 25¢ =75¢
then another quarter
75¢+25¢ = 100¢.
So, adding 1 nickel and 2 quarters to 45¢ makes 100¢.

b. 15¢ + _______ = 100¢

c. 57¢ + ________ = 100¢

d. ________ + 71¢ = 100¢

Question 2.
Solve using the arrow way and a number bond.

a. 79¢ + ________ = 100¢

b. 64¢ + ________ = 100¢

c. 100¢ – 30¢ = _______

Question 3.
Solve.

a. _______ + 33¢ = 100¢

b. 100¢ – 55¢ = ________

c. 100¢ – 28¢ = ________

d. 100¢ – 43¢ = ________

e. 100¢ – 19¢ = ________
