What do a thumb, the number three, and a thermometer all have in common? They all begin with a "th" sound!  In this worksheet your child will gain experience with beginning word sounds. He will first need to cut out the different objects pictured. He will then need to decide which words begin with the "th" sound. Have your child sound out the words, and then paste the ones that begin with a "th" sound to the page. When your child has finished, he will have created a "Th" book!
