We taped the box so the flaps of the box were close to the ground. The children really enjoyed searching for the missing bean bags. Here is a group gross motor activity game I did with my preschool co-op. You need a large blue tarp, sheet or felt etc. Place an alligator stuffed or plastic on sheet.
Children form a line behind.
As you cross the swamp you chant I'm walking, I'm walking, I'm walking across the swamp. I hope that alligator doesn't go chop. At this time you and the children make a alligator chomping gesture by bringing arms and hands down together. I hope that alligator doesn't go chomp. Can also do tip toeing, jumping etc.
