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.

Hello! Thanks for your interest!

This package contains:
6 problems for whole group mini-lessons
12 task cards
student recording sheets
student-friendly answer sheets
directions for a center
blank directions so you can customize directions

This has several problems you can solve as a group. My suggestion is to present the problem and have students work in groups and present the solutions. The problems have ‘extra information’ to promote critical thinking. In several problems, numbers are used that discourage the use of just changing fractions to improper fractions to subtract.

I do have an additional document that introduces addition and subtraction using common denominators that does not involve whole numbers. It is available on Teachers Pay Teachers. It is assumed that students working on these problems already understand the need for common denominators, but they have not worked with mixed numbers and regrouping. There are also a few problems that address the importance of the size of the whole, or having the same whole when making comparisons. Three cards review order of operations.

These are for the use of the purchaser only. I hope they are helpful with your students! 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!
