Area and Circumference of Circles-Digital Circuit Training (18 problems/cards)

This is a self-checking digital circuit activity on area and circumference of circles. There are 18 cards on 3 slides as each card contains one problem, it is the area to be found if it is given the circumference of a circle OR the circumference to be found if it is given the area of the circle. Students have to use the approximate value of the number pi 3.14 in their calculations.

Activity directions: Students begin with the problem #1, solve the problem, find the answer somewhere else on the slides and write “2” in the blank. Then student solve that problem (#2), search for the answer again and when find it write “3” in the next blank. Students continue in this manner until they return to the problem #1. They should solve all the problems before returning to the start point.

Answer keys are included. (There is also provided a black and white version of the cards.) I recommend the usage of a calculator to help students cope with all the problems on time.
