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.
Create this on my own. Pass out M on the first day during table work time. Depending on which color they have they must answer a question. You can do this activity through out the year changing up the questions!
