acute, obtuse ,and right angles

Even though I teach 2nd I run an enrichment math club for 2nd, 3rd, and 4th, and you might be able to stretch it and apply it. Here it goes:
1 )After intro. lesson of all the angles I begin by connecting two 12 in. straight edges (we don't have protractors) and measure angles around the classroom. ( > , <, or = a right triangle). We labeled objects by angles with a post it note to practice academic language. You could classify as well.
2 ) Next we went into the cafeteria (you might be able to go into a science lab?) and measured angles there. . . outside buildings might be good too. Of course most were right angles.This is where you might incorporate higher level concepts and have discussions.
3) Back in the classroom I passed out red vines and instead of using the straight edges for debriefing we used the licorice sticks. In order to eat them they had list or draw items in their math log. I myself had a large protractor I put on my elmo.
I hope this sparks an idea and is not too juvenile !
