Teaching tips and what to try next

Fits third graders who know facts with small factors and can multiply by 10. The real skill here is choosing the order, so ask your child to explain which pair they picked before writing anything. Facts with 0, 1 and 10 are in Multiplying by 0, 1 and 10, and order-only practice is in Commutative Property of Multiplication.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

When three numbers are multiplied, you can multiply any two of them first. For 4 × 5 × 2, multiplying 5 × 2 first gives 10, and 4 × 10 is easy. This is the associative property, and third graders are expected to use properties like it as strategies for multiplying. This third grade worksheet gives children a page of three-factor problems where a smart choice of pair makes the work easier.

The page has fourteen problems such as 3 × 2 × 5. Factors are 1 through 6 or 10, no problem has more than one factor of 1, and every product is 100 or less. Some problems contain a pair that makes 10 or a pair the child already knows well, and a factor of 10 appears now and then for practice with tens. Each of the ten versions has new problems and its own answer key.

How to use it: before your child multiplies, ask which two numbers they want to start with and why. Circling that pair, writing its product above it, and then multiplying by the third number keeps the steps clear. Try the same problem twice with a different first pair to show that the answer stays the same. A common mistake is adding one pair by accident, so have your child say "times" out loud at each step.

The answer key shows every product. For facts with 0, 1 and 10, try our Multiplying by 0, 1 and 10 worksheet. For more practice with small factors, try our Multiplication Facts 2-5 worksheet.
