This is a set of 24 task cards designed to give students practice calculating the area of a circle. Each card contains a diagram of a circle with either the diameter or the radius labeled. Each question is multiple choice.
These were created for above-level fifth grade math students who have just learned how to use pi (3.14) times the radius squared to find the area. I use them for small groups of students in my class while I work with other groups of kids. I typically run off multiple sets of cards so that kids can work in partners, with their own recording sheets. They would also work well for a math center. (I have some students who mix up the formulas for circumference and area and have made distractor answer choices to include the circumference intentionally.) I also offer a set of task cards that focus solely on circumference in a separate listing.
This is an 8-page PDF file that consists of 24 task cards (4 per page for 6 pages), a 1 page recording sheet for students, and a 1 page answer key.
