With the school year approaching, time to load up my Curriculum section. This addition is simple but useful. My plan for the year is to stick with groups as much as possible. Plenty on that in the very near future. And a nice group activity is puzzle for openers or days when lots of kids are gone on a field trip (a frequent occurance in Pre Cal). So I've got some 4x4 puzzles for Trig Identities, Radian/Degree conversions, and decimals. The decimals puzzle is a nice piece for boot camp, and it never hurts to try and spice up Trig Identities.
