Pumpkin Math

We have been using pumpkins to learn some valuable math skills!
First we learned what the word circumference meant and brainstormed different ways to measure the circumference of a pumpkin. Several students thought using a ruler would work so we tried that. It did not work. One student suggested using a cloth measuring tape, which was a wonderful idea except that we did not have any measuring tapes. 
We finally realized we could use a piece of string and wrap it around the thickest part of the pumpkin. Then we used our rulers to measure the string. We also estimated, counted and measured the vertical lines on our pumpkins. We compared the number of lines of larger pumpkins and smaller pumpkins. This week we will continue pumpkin math by weighing our pumpkins and figuring out their radius.
