Add and Subtract Fractions Task Cards, 4.NF.3 Centers:

These 24 task cards are aligned with Common Core Standard 4.NF.3: Adding and Subtracting Fractions. Several types of questions help you assess your students' mastery of adding and subtracting fractions.

4.NF.3. Understand a fraction a/b with a > 1 as a sum of fractions 1/b.

4.NF.B.3.A. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

4.NF.B.3.B. 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.

4.NF.B.3.C. Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.

4.NF.B.3.D. Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

Task cards are great for a whole-class game, math centers/stations, fast finishers, extra practice, homework, scavenger hunt, quiz-quiz-trade, morning work, small groups, or review for test.

Each card is numbered for your convenience, and there is a student recording sheet and an answer key included. The cards also include the CCSS in the lower left-hand corner. All task cards are included in color and in black and white for your printing needs.
