EnVision Math Topic 7 Review: Adding and Subtracting Mixed Numbers

Description

This is a basic review for EnVision Math (2020) Topic 7 that focuses on adding and subtracting mixed numbers, which I find to be the biggest weakness for students in this topic. It includes fifteen review problems, a student comprehension checklist, and an answer key. I assign this just before giving the Topic 7 Test.

CCSS5.NF.A.1

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.)

CCSS5.NF.A.2

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.
