What Is Benchmark MA.4.AR.1.1?

Students solve real-world problems with multiplication and division of whole numbers, including multiplicative comparisons ("6 times as many") and division problems with remainders.

The remainder must make sense in the story. Depending on the question, the answer could be the whole number part of the quotient, the quotient with the remainder, the next whole number up, or just the remainder.

Official benchmarkSolve real-world problems involving multiplication and division of whole numbers including problems in which remainders must be interpreted within the context.

On the FAST test: part of the Grade 4 reporting category Number Sense and Operations with Whole Numbers, which is about 31–37% of the test.

Worked Examples

Worked Example 1

Rounding Up Because of the Remainder

A ferry carries 9 cars per trip. 130 cars are waiting. How many trips does the ferry need to make?
  1. 1130 ÷ 9 = 14 R4 (9 × 14 = 126)
  2. 214 trips carry 126 cars, and 4 cars are still waiting.
  3. 3One more trip is needed.
Answer: 15 trips

Worked Example 2

Times as Many

Mia has 15 stickers. Her brother has 6 times as many. How many stickers does her brother have?
  1. 1"6 times as many" means multiply.
  2. 215 × 6 = 90
Answer: 90 stickers

Common Mistakes to Watch For

Ignoring the remainder

Wrong:The ferry needs 14 trips.

After 14 trips, 4 cars are left behind. The ferry needs 15 trips.

Adding for "times as many"

Wrong:6 times as many as 15 is 15 + 6 = 21.

"Times as many" means multiply: 15 × 6 = 90.

Helpful Math Tip

After dividing, ask, "What does the remainder mean in this story?" Is it people who still need a seat, or leftover items?
