The object of this game is for students to practice basic math subtraction facts (or missing addends) in an exciting way.
White Board and White Board Marker
Spiderweb Rug (or Spiderweb Game Board)
Spider Game Pieces
Students work with partners and take turns dumping spiders on the rug. Some spiders will land face up, some will land face down, and some will not even land on the rug. Students then discard the spiders that did not land on the rug and count the number of remaining spiders. This is their total. Students then count the number of spiders that are face up. This is one of the addends. Students write a subtraction equation on their white boards and solve it to find the difference.
This game could also be simplified as a basic counting game (count the number of spiders that are face up) for kindergarten or preschool. You could also use this game as an addition game (add up the number of spiders face up and the number of spiders face down on the board to find the sum.)
