Word Problems

What is the role of estimation in solving word problems?

• Estimation provides an exact answer to the problem.

• Estimation helps you get a rough idea of what the answer should be, allowing you to check if your final answer is reasonable.

• Estimation is not useful in solving word problems.

• Estimation only applies to numerical problems, not word problems.

What is an example of a multi-step word problem?

• If you have 10 apples and you buy 5 more, then give away 3, how many apples do you have left? You would first add 10 + 5 = 15, then subtract 3 to get 12 apples.

• If you have 10 oranges and you eat 2, how many oranges do you have left? You would subtract 2 from 10 to get 8 oranges.

• If you have 5 bananas and you buy 3 more, how many bananas do you have? You would add 5 + 3 to get 8 bananas.

• If you have 20 grapes and you give away 10, how many grapes do you have left? You would subtract 10 from 20 to get 10 grapes.

What does 'altogether' mean in a word problem?

• To find the total amount by adding numbers together.

• To subtract one number from another.

• To multiply two numbers together.

• To divide one number by another.

What is a common mistake when solving word problems?

• Misreading the problem or misunderstanding what is being asked, leading to incorrect calculations.

• Using complex formulas that are not necessary for the problem.

• Ignoring the units of measurement in the calculations.

• Rushing through the problem without checking the work.

What is subtraction used for in word problems?

• To find out how much is left or how much has been taken away.

• To calculate the total amount of items present.

• To determine the average of a set of numbers.

• To compare two different quantities.

What does 'how many are left' indicate in a word problem?

• It indicates that you need to use addition to find the total amount.

• It indicates that you need to use multiplication to find the total amount.

• It indicates that you need to use subtraction to find the remaining amount after some have been taken away.

• It indicates that you need to use division to find the average amount.

How do you find the total when adding two numbers?

• You multiply the two numbers together.

• You subtract the smaller number from the larger number.

• You add the two numbers together. For example, if Jordan read 485 pages last month and 391 pages this month, you calculate 485 + 391 = 876 pages.

• You divide the larger number by the smaller number.

How do you determine how much longer one activity took than another?

• Add the times of both activities together.

• Multiply the longer time by the shorter time.

• Subtract the shorter time from the longer time.

• Divide the longer time by the shorter time.

What is the importance of understanding key terms in word problems?

• It helps you memorize formulas more easily.

• It allows you to determine what mathematical operations to use, such as addition, subtraction, multiplication, or division.

• It makes word problems more interesting to read.

• It helps you solve problems faster without understanding them.

How do you calculate the change in temperature?

• Add the two temperatures together.

• Subtract the lower temperature from the higher temperature.

• Multiply the two temperatures together.

• Divide the higher temperature by the lower temperature.
