This story doesn't really go into the depthof what makes Pi like my reader, We Like Pi(e) does.The story, If You Give A Mouse A Circle delves moreinto how to use pi to get the circumference of a circle.I HIGHLY recommend that your students arefamiliar with Laura Numeroff's little mousecharacter before you use this for Pi Day.

Side Note: I know that you can use the formulacircumference = 2 x Pi x Radius (2 Pi R)but that just seems too complicated for my little ones.I can barely type that out on my computer sinceI don't have a key for Pi.....sooooo.....I stuck with circumference = Pi x Diameter

At this point, teachers of older studentsmay want to stop the story and haveyour students figure out the math withoutthe calculator. I know that for my 6 year olds...we would definitely need a calculator!
