I created this project my first year of teaching (we won’t talk about how long ago that was). It used to be a teacher-guided activity, but with the use of technology, it’s now a perseverance activity that meets the Geometry construction standards for constructing an equilateral triangle and regular hexagon. We also have a discussion about the ratio of the circumference to the diameter of a circle when they ask the question, “Why doesn’t this fit exactly?”
I’ve included a link to the doc with animated gifs to guide the students through construction. Seriously, try to not help them. They can figure this out.
Here’s a small gallery of current and past pumpkins. It really is a fun activity that meets our standards. Our goal is to Make Math Not Suck!
