It's great to reward students with a choice of different activities when we meet. The lego center has been a HUGE hit. I need more space and more pieces:) It has been really interesting to see what kids come up with. I have students coming in at recess and lunch recess to work. I love that it fosters spatial reasoning and creativity at the same time.
Here are a few of the creations that have been built. Students may put a completed form on a shelf for a day, but after that, they get taken apart and the pieces go back into circulation.
I don't have any mini figs, so a couple kids created their own.
