About this worksheet
Facts with 0 and 1, including a few missing numbers, like ? × 1 = 7.
What kids practice
A few rules make multiplication much easier. Turn-around facts have the same product (3 × 7 = 7 × 3). A hard fact can be broken into two easy ones (6 × 7 = 6 × 5 + 6 × 2). Any number times 1 is that number, and any number times 0 is 0. Children also look for patterns in the times table, like products of 5 always ending in 0 or 5.
Watch for
- Thinking any number times 0 is that number, like 6 × 0 = 6.
- Breaking apart a fact but adding only one part back in.
- Thinking turn-around facts work for subtraction too. 7 − 3 is not 3 − 7.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full multiplication properties and patterns guide for 3rd grade.
