I like to use card sorts in my math classroom. I've been working on various sets. Recently I created a card sort for identifying the difference between linear and nonlinear functions. The card sort has 20 cards - 12 equations and 8 tables. Get the link below to the set of cards!
When I use card sorts, I don't always tell students the categories I'm looking for. I might tell them how many categories I want them to create. Keeping the categories open allows for a rich discussion about what they see on the cards, and how they choose to sort them. It allows students to show off their understanding of math vocabulary and to make connections that I might not have thought of.
After sorting the cards, I like to ask students to create another set of cards - for each category. In creating their own set, they demonstrate understanding of the concepts. You can use student create cards for additional practice during the unit!
Check out the card sort ... it's free ... try it and let me know how it works for you!

PS ... How would you use this card sort? What cards would you add? What concepts work well as a sorting activity?
