I always try to have my students that have special needs do the project that the class is working on (with modifications). However, an hour is a long time for them to stay focused & not distroy the work they are doing. So after about a half hour, I'll take the work from the special needs students, and give them the Mega Blocks to build with. THEY LOVE THEM!!!! The structures they've built are pretty amazing. I found these Mega Bloks at Wal-Mart.
