Subjects: math

Grades: 5,6,7,8

Description: This 24-card deck is a great way for your math students to practice finding the circumference of a circle. Includes a variety of diagrams with a given radius, diameter, or some that require students to use a circle on a grid to determine the radius before using the formula for circumference. The first 3 cards are designed to make sure students are able to identify the radius and diameter of a circle and the correct formulas that can be used to calculate the circumference. The remaining 21 cards give students a diagram and ask them to find the circumference rounded to the nearest tenth. Students can use the pi button or 3.14. Solutions for both are programmed in. Don't forget you can hide any cards you don't want students to see.
