Third grade enjoys a reward for completing and turning in homework on time. Each week we have a Fun Friday. These range from game days, outside games, to movies, STEM activities or in this case, cooperative learning. Creating a tower using rubber bands and drinking cups was puzzling at first. When the first group figured it out the room buzzed with excitement as everyone built the standard tower and some interesting variations. No hands! Unstacking and re-stacking, all with five or six "handles" of rubber bands. Creativity, Persistence, Focus.
