Pattern Blocks: Equivalent Fractions
As you can see, they even started getting into adding fractions with different denominators. When I asked them why you could add different fractions, they were able to relate it back to equivalent fractions with common denominators. Once we transitioned all that concrete work to the pictorial and abstract representations, they picked up on it quickly. Any that struggled were able to fall back to the pattern blocks again to help them solve the problems. Totally worth two days of math time, to save me a week of teaching fractions five different ways looking for a way that would stick with everyone.
