I'm so happy to be able to get my grade 7&8s using manipulative for math. Yesterday I pulled out a big tub of algebra tiles and I had then build arrays to model multiplication of fractions. It was amazing to watch all the different ways they tried to model 4/5x2/3. They were actively engaged and discussing with partners. There even was heated debate. It did take hem a lot longer than just following the formula, but I think some of them actually started to understand why multiplying fractions results in smaller fractions.
"Can we cut these ones in half?"
