The Elkonin Box Phoneme Magnetic Dry-Erase Boards has 8 reusable phoneme frame whiteboards that help pupils develop phonemic awareness and phonics skills. Use these boards to help children segment words into phonemes; identify beginning, middle and ending sounds; blend phonemes to create words; and draw or write words. The built-in slider on each phoneme frame whiteboard offers a tactile way to support phoneme segmenting and blending as children learn to read 2-, 3-, 4- and 5-sound words.
