Subtract a mixed number from a mixed number.
Before the Problem Set, you could have students play a modified version of “Rolling Fractions” found on p. 63 of the Georgia Standards of Excellence Curriculum Frameworks: Mathematics GSE Fourth Grade Unit 4: Operations with Fractions. You should modify it by having students subtract a fraction from a mixed number and not a mixed number from a mixed number. You may also modify it by giving students more denominators to choose from in #1 of the directions (e.g., include all denominators students are expected to work with in Grade 4, including 2, 3, 4, 5, 6, 8, 10, and 12).
If you need to adapt or shorten this lesson for remote learning, we suggest prioritizing Anchor Tasks 2 and 3 (benefit from worked examples). You could consolidate these as one Anchor Task using Anchor Task 2 Part (a) and (c) and Anchor Task 3 Parts (b) and (c) (or even just Part (c)).
