Puzzle pieces that progressively build to teach the alphabet. A tactile emery surface helps children recognise each letter's shape; then match it to a corresponding image. Each letter puzzle then builds to form a larger, rectangular alphabet puzzle. Individually sized puzzle pieces teach childern to distinguish longer and shorter words. Children learn to recognise the alphabet, read their first words and develop their fine motor skils. Features 26 two-piece alphabet puzzles. Made from chunky cardboard.
