I started by showing the class this video. This is an EXCELLENT 9 minute video from teachertipster.com. The guy in this video is so funny. Some of the video addresses teachers directly, but the students loved watching it to get an idea of what would be expected of them.
I had the kids bring in their Angry Birds stuffies and various shapes of boxes, which they then wrapped THEMSELVES (hurrah for intermediates!) in bulletin board paper. I also had them use poster board and 3-D shapes to make their own "nets" and cover them for the shapes that weren't represented.
They then labeled them with the 3-D shape name and money amount they thought the shape would be "worth" if it was knocked down. We went with $0.25, $0.50, $0.75, and $1.00. This helped them practice adding decimals and writing money amounts correctly.
We measured a "safe throwing distance" with a meter stick and converted it to feet. Gotta love anytime you can sneak in converting measurements!
Each new team got to set up the tower in any way they wanted, resulting in about 5 completely different set-ups.
Have you used Angry Birds in your curriculum? I'd love to know how!
