Snowball Fight...kids write 3 things about themselves on a sheet of white paper. They do not write their names on the paper. Wad it up and on your command, have a "snowball" (or baseball) fight. At the end of 1 minute, each student grabs the nearest snowball and tries to guess who wrote it. Would be great at the beginning of the year!
These upside down crates with fabric cushions on top are a great idea for students in a classroom used for alternative seating for students with disabilities. Sometimes the regular seating can be restrictive and at the wrong level. Create your own, they are cheap too!
