Day 13

Yesterday I brought in my toaster. They drew quadrilaterals on shrink film and recorded side lengths. I shrunk 'em, and today we measured the "after" side lengths. In one class, it worked perfectly and showed the proportion. In the other class, it wasn't as tidy. I just had to shrug and say "real life is never as tidy as the problems in your math book!"

I had a moment of panic when the shrink film started to curl.  Fortunately I decided to "keep calm and read the instructions" that said curling was normal, and it would lay flat before it was finished.
