About this worksheet

What students practice

Students predict whether a product is greater than, less than, or equal to a factor by comparing the other factor to 1.
Students compare products that share a factor without multiplying.
Students explain why multiplying by a fraction equal to 1 makes an equivalent fraction.

How to use

Use after students can multiply a whole number by a fraction. Have them make every prediction before they multiply, then use the check problems to confirm their thinking.
