This activity is designed to help students better understand how to decompose fractions into a sum of fractions using models and equations. You can use this as practice in the classroom, homework, or as an assessment. It is aligned with CCSS.Math.Content. 4.NF.B.3b: Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.
