3rd Grade Multiplying Three or More Numbers Worksheet: 6 Items
A product can have more than two factors. This 3rd grade multiplying three or more numbers worksheet shows children how to handle a chain of three, four or five numbers. There are 6 items, labeled a to f, and each one comes with four answers to choose from. The factors are small, mostly one digit, with a 21 and a 10 among them. A little yellow bird with a feather and a bow stands at the bottom of the page. Page two ticks the right answer for each item.
Two at a time, in any order
Children multiply two factors, then multiply that result by the next factor. The associative property says the grouping does not change the product, so your child can choose an order that makes the work easy. In a, 21 × 5 × 2 is easier as 21 × 10, which is 210.
The same trick helps in c. There, 5 × 2 makes 10 and 10 × 10 makes 100. So 5 × 10 × 6 × 2 becomes 100 × 6, or 600. In b, the factor 1 changes nothing. The product is just 7 × 9 × 3, which is 189.
At the table: zero and close choices
Item f begins with 0. One factor of zero makes the whole product zero. As a result, your child can tick 0 without any other work. That is the rule to multiply by zero, and it saves time.
Item e, 6 × 6 × 6, needs care: 6 × 6 = 36, and 36 × 6 = 216. The wrong choices 186, 196 and 206 are close on purpose, so a guess will not do. Several products go past 100, a bit beyond the third grade goal. So let your child use the grid for the larger steps.
After the page: cover the choices
For a harder round, cover the four boxes with a strip of paper. Your child works out each product first and only then looks for it, which turns the multiple choice page into real practice. Make up a chain such as 2 × 3 × 5 together, and compare all the ticks with the answer key on page two.
