Squashy Putty (a homemade version of Silly Putty) is a lot of fun to make and use while studying the letter S (or P). It is very inexpensive and the children (as well as adults) love it.
To make homemade squashy putty you need:
A medium size bowl
liquid starch (in the laundry detergent section in the grocery store)
water for rinsing
food coloring (optional)
Pour ten tablespoons of white glue into a medium size bowl. Add five tablespoons liquid starch. Let it set for five minutes. Add food coloring if desired. Using gloves, mix well with hands until all liquid is absorbed. Rinse. Divide into five pieces and store in plastic baggies. Yield: 5 pieces of squashy putty.
Use the squashy putty to form a snake and shape into the letter s.
