What Is Benchmark MA.3.AR.3.2?
Students decide whether a whole number from 1 to 144 is a multiple of a one-digit number. A multiple of 6 is any number you get by multiplying 6 by a whole number: 6, 12, 18, 24, and so on.
To check, use multiplication (is there a whole number that times 6 makes it?) or division (does it divide evenly with nothing left over?).
Official benchmarkDetermine whether a whole number from 1 to 144 is a multiple of a given one-digit number.
On the FAST test: part of the Grade 3 reporting category Number Sense and Multiplicative Reasoning, which is about 23–29% of the test.

Worked Example 2
Not a Multiple
Is 75 a multiple of 4?
- 1Multiples of 4 are all even numbers.
- 275 is odd, so it can't be a multiple of 4.
- 3Check: 4 × 18 = 72 and 4 × 19 = 76, so 75 is skipped.
Answer: No, 75 is not a multiple of 4
Common Mistakes to Watch For
Stopping at the 10 times table
Wrong:96 is not a multiple of 8 because the 8s facts stop at 80.
Multiples keep going. 8 × 12 = 96, so 96 is a multiple of 8.
Mixing up factor and multiple
Wrong:7 is a multiple of 28.
28 is a multiple of 7, and 7 is a factor of 28.
Helpful Math Tip
Skip count by the number out loud: "6, 12, 18, 24..." If you land exactly on the target number, it's a multiple.
