Below are sample questions representative of the exercises included on this worksheet and related 3.144 Mathematical Communication and Explanation Choices skill assessments:

Problem 1Difficulty: Mastery

A student rewrites 47 + 36 as 49 + 34 and says the sums are equal.

Which statement best explains why changing the addends this way keeps the sum the same?

ABecause changing addends always changes the sum.

BBecause you can swap any digits between numbers and keep the sum the same.

CBecause adding 2 to one addend and subtracting 2 from the other keeps the total unchanged.

DBecause 49 + 34 is only an estimate of 47 + 36.

Solution & Explanation:The total changes by +2 and −2 at the same time. Those changes cancel out, so the sum stays the same.

Problem 2Difficulty: Mastery

A student says, “If 0 is multiplied by any number, the product is 0.”

Which statement best explains this using equal groups?

ABecause 0 groups of something means there are no items at all, so the total is 0.

BBecause 0 is the biggest number.

CBecause multiplying by 0 is the same as multiplying by 1.

DBecause 0 added many times becomes 1.

Solution & Explanation:Multiplication can mean 'number of groups.' If there are 0 groups, the total items is 0, no matter the size of each group.

Problem 3Difficulty: Mastery

A student says, “I can check 468 − 295 by adding: 295 + 173 = 468.”

Which statement best explains why this check works?

ABecause addition always gives the same answer as subtraction.

BBecause 295 + 173 must be 295.

CBecause you can only check subtraction by multiplying.

DBecause the difference is the missing addend that brings 295 up to 468, so adding it should return the original number.

Solution & Explanation:If 468 − 295 = 173, then 295 + 173 must equal 468. Using inverse operations checks the result.
