Product Description
Fifth Grade Common Core Objectives:
Use equivalent fractions as a strategy to add and subtract fractions.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.

This includes:
7 tasks to use for whole or small group
teacher notes with additional problems for small groups
12 task cards
student recording sheets for task cards
answer keys for all problems
directions for task cards
blank directions for task cards to individualize instruction

These tasks help introduce addition and subtraction using common denominators. Although some solutions are more than one, problems generally do not have mixed numbers. Once students develop an understanding of problem solving with fractions and the need for common denominators, I introduce mixed numbers. I do have a similar product with problem solving and addition of subtraction of mixed numbers. It is available on Teachers Pay Teachers.

Please see the preview slide for sample tasks.

I hope this is helpful! I welcome your comments and suggestions. If you have a question, please leave it on my TPT page. I am happy to answer any questions!

Thank you!
