Math Cards Activity

I recently attended an exciting ISACS math workshop given by Jo Boaler from Stanford. Her webpage,, features lots of low floor-high celing math tasks for all grade levels. I was intrigued by the Math Cards activity and its statement of purpose, so I decided to make a set for my math group.

“Many parents use ‘flash cards’ as a way of encouraging the learning of math facts. These usually include 2 unhelpful practices – memorization without understanding and time pressure. In our Math Cards activity we have used the structure of cards, which children like, but we have moved the emphasis to number sense and the understanding of multiplication without any time constraints.”

Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning.They justify their conclusions, communicate them to others, and respond to the arguments of others. We have a classroom environment that nurtures these proficiencies. I know you will be delighted while watching this video of one math group as they work together to match all the cards. It is a testament to their skill in communicating and  attending to precision.
