Composing and Decomposing Fractions

Composing and decomposing fractions helps students visualize fractions in a way that makes problem-solving easier. These activities provide support as you teach your upper elementary and middle school students about composing and decomposing fractions.

Pattern Block Fractions

Students will compose and decompose fractions using pattern blocks, and they'll use the information the uncover to identify equivalent fractions.


  • pattern blocks


  • Have students find as many ways as possible to duplicate the hexagon using the other pattern blocks.
  • Have students write an equation that represents how each of the fractional parts can be added to create the whole hexagon.
  • Have students identify other equivalent fractions using pattern blocks.

Creating Fraction Strips

Students will create their own fraction strip manipulatives to explore composing and decomposing fractions.


  • colored card stock cut into 9' x 2' strips
  • scissors
  • gallon-sized bags
