"A puzzle by Sam Loyd. The red strips are twice as long as the yellow strips. The eight can be assembled to form two squares of different sizes. How can they be rearranged (in the plane) to form three squares of equal size?" Interesting brainteaser or problem that could act as a warmup. You could make these strips into manipulatives in Inspire or give the students physical strips to help with the visualization process. I'm sure there's math here, I just don't know what it is...

"Solving a math problem means unfolding a mystery, enjoying the pleasure of discovery. But in every geometry lesson that year, I blundered along and blurted out the secret. With a few sentences, I'd manage to ruin the puzzle, ending the feast before it began, as definitively as if I'd spat in my students' soup. Math is a story, and I was giving my kids spoilers." This post speaks directly to math, but can be applied to any content. When we provide students with the answers rather than developing lessons that let the students ask (and answer questions), we take the fun out of learning.
