Classic Sandpaper Phonograms - Greek Alphabet

A wooden board with sandpaper that represent phonograms (ch, sh, ng,gn etc.). This set contains 18 pairs of phonograms. This material helps the child make a connection between the sound and the feel of the letters, as the child uses this material by holding the wooden board with its non-dominant hand and traces its index and middle finger with his dominant hand on the sandpaper phonograms.
This is a teaching material, not a toy.
