Tie 3 feet of string to a wooden spoon. Attach a magnet to the end of the string. Cut and laminate many different colored and sized frogs from construction paper or card stock. Attach a paper clip to each frog. Spread the frog shapes on the floor and let the children try to catch the frogs. Once they get the hang of it, have them work to catch a specific frog (the red frog or the biggest frog).
