Problem 1:

Solve a multi-step word problem using a tape diagram.

The city flower shop sold 14,594 pink roses on Valentine’s Day.
They sold 7,857 more red roses than pink roses. How many pink
and red roses did the city flower shop sell altogether on
Valentine’s Day? Use a tape diagram to show your work.

Problem 2:

### NYS Math Module 1 Grade 4 Lesson 12 Problem Set

Directions: Estimate and then solve each problem. Model the problem with a tape diagram. Explain if your
answer is reasonable.

1. For the bake sale, Connie baked 144 cookies. Esther baked 49 more cookies than Connie.

a. About how many cookies did Connie and Esther bake? Estimate by rounding each number to the
nearest ten before adding.

b. Exactly how many cookies did Connie and Esther bake?

c. Is your answer reasonable? Compare your estimate from (a) to your answer from (b). Write a
sentence to explain your reasoning.

4. During National Recycling Month, Mr. Yardley’s class spent 4 weeks collecting empty cans to recycle.

a. During Week 2, the class collected 1,256 more cans than they did during Week 1.
