4.3(B): Decompose a fraction in more than one way into a sum of fractions…
Decompose a fraction in more than one way into a sum of fractions with the same denominator using concrete and pictorial models and recording results with symbolic representations.
The Texas Essential Knowledge and Skills (TEKS) for Mathematics outcome 4.3(B) (Number and operations) for Grade 4 says: “Decompose a fraction in more than one way into a sum of fractions with the same denominator using concrete and pictorial models and recording results with symbolic representations.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Texas Essential Knowledge and Skills (TEKS) for Mathematics.
Fair Shares: Fractions and Decimals Grades 3–4
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.
