Solving Multiple Step Word Problems in Addition and Subtraction

What should you do first when faced with a problem involving multiple steps?

• Start solving immediately

• Read the problem multiple times if necessary

• Ask someone else for the answer

• Skip the problem

How many stamps do Joe and Steve need to complete their collection?

• 65 stamps

• 87 stamps

• 246 stamps

• 152 stamps

What is the first step in solving Joe and Steve's stamp problem?

• Estimate the answer

• Calculate the total stamps they already have

• Determine how many more stamps are needed

• Use a number line

How many stamps do Joe and Steve currently have together?

• 152 stamps

• 246 stamps

• 200 stamps

• 94 stamps

How did the narrator choose to add the numbers 87 and 65?

• By rounding them first

• Using a calculator

• By place value

• Guessing the answer

What tool did the narrator use to solve the 'how many more' part of the problem?

• Calculator

• Abacus

• Graph paper

• Number line

How many more stamps do Joe and Steve need to reach their goal?

• 246 stamps

• 94 stamps

• 152 stamps

• 200 stamps

Is the solution to how many more stamps are needed reasonable?

• No, because it is too low

• No, because it is too high

• Yes, because it is exactly the estimate

• Yes, because it closely matches the estimate

What was the purpose of estimating in the problem-solving process?

• To make the problem harder

• To avoid calculating the exact answer

• To check the reasonableness of the answer

• To use less time solving the problem

Why is it important to evaluate if the answer makes sense?

• To finish the problem faster

• To make the problem easier

• Because it's a guess

• To ensure accuracy
