Appeal to the senses while learning the alphabet and spelling simple words. Spell out sight words and students' names. We have doubled up on commonly used letters. Use the letters on a light table to create glowing words. Inside each letter is a small disc. Ask students to move the disc all the way around a letter to practice fine motor skills. Layer the letters to make new color combinations. Note: All vowels are red. Includes: 38 letters up to 3.25" x 4.75" (9 x 12 cm) and guide.
