Unit 9: Add & Subtract Fractions
Unit 9: Add & Subtract Fractions
5-09+Family+Letter_Add+and+Subtract+Fractions.pdfFocus Question: How do I add & subtract fractions?
This is our first year with this new curriculum, Reveal Math.
This ninth unit is all about understanding the different strategies of adding and subtracting fractions. Within this unit, we will look at estimating, representing/modeling fractions, adding and subtracting with unlike denominators, adding and subtracting with mixed numbers, and adding and subtracting fractions in word problems.

Videos/skills we need to review before we start this lesson!
Reveal Math 9.1 - Estimate Sums and Differences of Fractions
5.NF.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.
Reveal Math 9.2 - Represent Addition of Fractions with unlike denominators
5.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 or difference of fractions with like denominators.
Reveal Math 9.3 - Add Fractions with Unlike Denominators
5.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 or difference of fractions with like denominators.
Reveal Math 9.4 - Represent Subtraction of Fractions with Unlike Denominators
5.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 or difference of fractions with like denominators.
Reveal Math 9.5 - Subtract Fractions with Unlike Denominators
5.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 or difference of fractions with like denominators.
Reveal Math 9.6 - Add Mixed Numbers with Unlike Denominators
5.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 or difference of fractions with like denominators.
