Overview:

To decompose means to break apart. Students already decomposed whole numbers with number bonds, tape diagrams, and place value charts. In fourth grade, they will decompose fractions.

Content Standard(s):
 Mathematics MA2019 (2019) Grade: 4 15. Model and justify decompositions of fractions and explain addition and subtraction of fractions as joining or separating parts referring to the same whole. a. Decompose a fraction as a sum of unit fractions and as a sum of fractions with the same denominator in more than one way using area models, length models, and equations. b. Add and subtract fractions and mixed numbers with like denominators using fraction equivalence, properties of operations, and the relationship between addition and subtraction. c. Solve word problems involving addition and subtraction of fractions and mixed numbers having like denominators, using drawings, visual fraction models, and equations to represent the problem. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.15 Model decomposing fractions having like denominators, using visual fraction models (limit to half and fourths).
