What is a “Sound Smash ABC” Book? A “Sound Smash ABC” Book is a book designed for children to practice their beginning sounds. Each letter of the alphabet has a two-page spread. Kids can use this space to fill all sorts of things that start with the letter on that page! My favorite… Cut out pictures from an old magazine, and SMASH them on the page! Kids will have a great time with this! Plus, they can practice their cutting and pasting skills too!!
