Does your child have pronunciation issues with some letter sounds? Here is an easy and inexpensive activity you can put together to help strengthen the muscles of his mouth and lips.
Cut out two identical shapes in the paper. I have access to a Cricut machine and used that to cut out my frog and my fish but they do not have to be such complicated shapes. Circles, squares and triangles will work too.
Use a glue stock to glue two identical shapes together, leaving a gap at the bottom that is not glued shut. Once the glue dries, insert a straw in the gap at the bottom. Ask your child to blow through the straw and that will send your shapes into flight.
