Deals with finding the area of a circle; planets are on the first page. The second/backside of the page has students find 5 circular shapes to trace on the paper and are asked to find the circumference of that shape. Originally created for Grade 7, can be used as review for older grades.
*I chose to use planets in this way so as to get my students to use larger, more complex numbers. Change the formula to a spherical area rather than circular area for the appropriate age level.
