Card Sorts can make excellent critical thinking activities. In this sort, students have 12 statements. They must decide if the statements are true or false. Students are determining key characteristics of quadratics in the exercise. Asking students to justify their choices and to “correct” the false statement would be a good way to increase the level of thinking required.
This activity works well as practice or as a formative assessment tool. It can be done individually or with a partner. It would also work well as a station activity.
I use this activity on Day 2 of our Quadratics unit in Algebra 2 to assess our first lesson on characteristics. I have also used it as a partner quiz mid-unit.
Other activities that coordinate with this one include:

Quadratics Graphic Organizer - Comparing Forms of Equations
