I Can apply strategies I have learned to solve addition and subtraction problems.

Step It Out

Question 1.
Kaya uses tiles to make a design.
Write an addition or subtraction problem about the tiles. Choose a strategy to solve your problem.
HMH Into Math Grade 3 Module 10 Lesson 5 Answer Key Choose a Strategy to Add or Subtract 1
Answer:
Nery used square tiles and triangle tiles to make a tower? how many tiles she used in all?
Number of square tiles = 502
Number of triangle tiles = 225
let t be the total tiles
t = 502 + 225
t = 727

Turn and Talk What strategy did you choose? Explain why you chose that strategy.
Answer:
I have choose squares and triangles
To make a tower I used the both tiles so I choose addition.

Question 2.
How many more trapezoid tiles are there than triangle tiles in Kaya’s kit?
HMH Into Math Grade 3 Module 10 Lesson 5 Answer Key Choose a Strategy to Add or Subtract 2
A. Write an equation to mode! the problem.
Answer:
Trapezoid = 483
Triangle = 225
t = 483 – 225
t = 258
I used subtraction equation.

B. Estimate:
Answer:
483 is rounded to 500
225 is rounded to 220
500 – 220= 280

C. Show two ways to solve the problem.
Answer:
First way is estimating
Second way is doing the equation and finding the appropriate answer.

D. How many more trapezoid tiles are there than triangle tiles?
Answer:
280 more trapezoid tiles are there than triangle tiles

Turn and Talk What strategies did you choose? Explain why the strategies work for the problem.
Answer:
I have used addition and subtraction strategies to do the problems.
