This is a standard fukuwarai game, made for a Halloween lesson. Fukuwarai is a Japanese game, similar to pin the tail on the donkey, where a bind folded person must finish a face as accurately as possible.
Print, cut, and laminate a set for each group (~4 kids per group). One set includes the pumpkin, two eyes, a nose and a mouth.
Make the size pretty large as the small pieces can get lost easily.
Acquire something to use as a blindfold for each group.
