This is sheet #180124601.
How to do it
- Shade the first fraction going up and down.
- Shade the second fraction going across.
- Count the boxes shaded twice and write the product.
Teaching tip
Colored pencils help. Two different colors make the boxes shaded twice easy to count. This sheet is aligned with Common Core 5.NF.B.4.
About this worksheet
Squares to shade for fraction multiplication problems. Fewer has 4 problems with the grid lines drawn and the first fraction shaded, Standard has 6 with the grid lines drawn, and More has 8 on blank squares. Includes an answer key with the shading.
What kids practice
In 4th grade, students multiplied a whole number by a fraction, like 3 × 2/5 as three groups of 2/5. Now they multiply a fraction by a fraction. An area model shows why 2/3 × 3/4 = 6/12: the part shaded twice is 6 of 12 boxes. From there, students use the rule of multiplying the top numbers and the bottom numbers, find a fraction of a number, like 2/3 of 12, and reason about whether multiplying by a fraction makes a number bigger or smaller. They also see that a fraction is a division, like 3 ÷ 4 = 3/4, and divide unit fractions and whole numbers, like 1/3 ÷ 4 and 4 ÷ 1/3.
Watch for
- Finding a common denominator first, as if adding.
- Multiplying the top numbers but keeping the bottom number the same.
- Multiplying a whole number by both the top and the bottom number.
- Expecting multiplication to always make a number bigger.
- Mixing up 1/3 ÷ 4 (a smaller piece) and 4 ÷ 1/3 (how many pieces fit).
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full multiplying and dividing fractions guide for 5th grade.
