This set of 24 task cards provides students with practice on various fractions concepts. Students will be asked to decompose fractions, add and subtract fractions with like denominators, add and subtract mixed numbers with like denominators, draw models and number lines to explain their thinking, as well as solve word problems where they must add or subtract fractions.
A recording sheet for students and an answer key for teachers is provided.
This activity is aligned to the following Common Core standards.
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.
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 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.
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.
I hope you and your students find this resource beneficial and engaging! Please remember to leave feedback!
