This Kagan style activity gives all students the opportunity to practice combining like terms, while being held individually accountable for their own work!
This activity is differentiated by including different levels of cards. The easier cards stick to adding and subtracting basic terms, while the more challenging level includes combining like terms using the distributive property. I have used this activity with students in pre-algebra through algebra honors courses, as it is able to be adapted by the students to the level that they need.
My students always enjoy playing this "game"--even though there are no points, no prizes, and no competition! It is a great way to encourage communication and collaboration between students, without just giving them "group work".
