Last year was our first year with Common Core and regrettably, I didn't do as great of a job teaching 3.MD.8 in a conceptual way as I could have. But with some ideas from a talented teammate and some of my own creativity, we are now masters of perimeter! We started by exploring with pattern blocks and creating ponds.
Finally, we've started to compare figures with the same perimeter but different area. We read another great book called Chickens on the Move and students modeled the coops with paperclips.
