Reasoning enables them to explain why two different fractions can represent the same portion of a whole (4.NF.1). The basic meaning of decomposition is to split or break up. They proceed to investigate this concept with the use of tape diagrams and area models.
A folded paper activity allows them to see that, when the number of fractional parts in a whole increases, the size of the parts decreases.

As students continue working with decomposition, they represent familiar unit fractions as the sum of smaller unit fractions.

The introduction of multiplication as a record of the decomposition of a fraction (4.NF.4a) early in the module allows students to become familiar with the notation before they work with more complex problems. Updated: Table of Contents Place Value Composing and Decomposing Numbers Lesson Summary Frequently Asked Questions How do you explain decomposing numbers Decomposing. They proceed to see that representing a fraction as the repeated addition of a unit fraction is the same as multiplying that unit fraction by a whole number. Students begin Topic A by decomposing fractions and creating tape diagrams to represent them as sums of fractions with the same denominator in different ways (4.NF.3b).
