Candy Cup
Directions:
 Each group of 3 or 4 students will
receive a whiteboard, marker, paper
towel for an eraser, and plastic cup.
 Students will have 2 to 4 minutes to
work as a group to complete a
problem and place the final agreed
upon answer on the whiteboard.
(Each individual must have the work
shown on their own paper.)
 Each team with the correct answer
will receive an integer chip in their
cup. Any member of the group can
be asked to explain their answer so
work together!
 At the end of the game, groups will
cash in their integer chips for a reward
to divide evenly among the team.
