It can also be done with a regular classroom or buddy classes! Here's a video version of the process and the math: http://www.youtube.com/watch?v=TFvRc3CqXv0 www.FamilyMathNight.com
Scrabble Board Sign-In Sheet: This was a super fun Family Math Night activity! I made a scrabble board for each grade level. The challenge was to see which grade level could get the highest score by the end of the evening.
