Do you remember Shrinky Dinks from the good ole days? You can still find them in some places but they can be too expensive to buy for a whole class. I have a cheaper alternative that will have you dumpster diving like a pro.
All you need are some permanent markers, an oven (in my case, a toaster oven), and some #6 plastic with this symbol on it:
For Mother's Day my class made their mothers a Shrinky Dink key chain. I gave them some clip art heart samples for them to trace. Once the plastic shrunk I added a jump ring and some key chain hardware that I found at Walmart. I think they turned out really cute.
