Add and subtract fractions with like denominators, including mixed numbers and fractions greater than one (addition only in this unit).
The Florida's B.E.S.T. Standards for Mathematics outcome MA.4.FR.2.2 (Fractions) for Grade 4 says: “Add and subtract fractions with like denominators, including mixed numbers and fractions greater than one (addition only in this unit).” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Florida's B.E.S.T. Standards for Mathematics.
Fair Shares: Fractions and Decimals Grades 3–4 · partly supports this outcome
Is half always the same size? Where does three-quarters stand? Why is 3/4 + 2/4 not 5/8? Who jumped further, 1.4 m or 1.35 m? Four hands-on lessons where students fold, stand on a giant number line, measure recipes and measure their own jumps to make sense of fractions and decimals.
- Which recipe makes more? 50–60 min
Teams measure three trail-mix recipes with fraction cups and dry rice, and find that 3/4 cup plus 2/4 cup overflows the 1-cup mark. Students add and decompose fractions with the same denominator, catch the 'add the bottoms too' mistake with real evidence, and compare totals greater than one.
