Add Fractions with Regrouping 4-99

Transition to adding 2 fractions with equal denominators and sums greater than 1. What's 3/4 + 2/4? Their units are the same – they have common denominators – so add their quantities or numerators. 3 fourths + 2 fourths = 5 fourths, or 1 and 1 fourth. Using fraction notation, 3/4 + 2/4 = 5/4 = 4/4 + 1/4 = 1 1/4.
