My initial hope was to laminate these cards, so student could write their partial areas on the cards before passing them to the next partner. However, this didn't happen. I just ran out of time. That's my next step.
I'm attaching the PDF. I think I've fixed all the weird measurements. If you catch one, be sure to let me know.
Also, I know problem #1 is weird... it's really just two steps - area of a trapezoid and of a rectangle, but I wanted to split it into three to show kids you could do it with rectangle/triangles rather than the trapezoid.
