"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...
