Add and Subtract Fractions (A) WORKSHEET
Suitable for Grades: 4th Grade
CCSS: 4.NF.B.3.A, 4.NF.B.3.B
CCSS Description: Understand a fraction a/b with a > 1 as a sum of fractions 1/b. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.lem.
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. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.

Add and Subtract Fractions (A) WORKSHEET DESCRIPTION
This worksheet is the first in our differentiated series for students and uses bar models to aid students in adding fractions with the same denominator. Throughout, your learners will shade bar models by given fractions and use these to complete additions. All the bar models are the same size and have been split into the appropriate number of ‘pieces’ already. Questions have been carefully chosen to highlight commutativity too.
