This is always an activity filled with smiles and giggles as the children explore symmetry by cutting out an abstract shape from a folded piece of paper. Children fold a paper in half, draw a squiggle, cut it out and see what it looks like to them. Most often, it will look like some sort of alien from outer space, so the students have fun creating a name and environment for their creature. This activity provides a directions card to place in a center. The directions are written in easy to follow language for primary students. All you provide is the paper, scissors, and crayons, then sit back and watch your little ones explore and create "Creatures from Planet Symm."
This idea was created by Terry Palmieri and has been used with much success in my 1st and 2nd grade math classes.
