Add Fractions with No Regrouping 4-98
Generalize from whole numbers, to adding fractions with equal denominators. What's 3/6 + 2/6? To make sense of fraction notation, write units explicitly. 3 sixths + 2 sixths = 5 sixths, so 3/6 + 2/6 = 5/6, not 5/12. Develop modeling and drawing skills on a number line to lay the foundation for the other 3 operations.
