Preschoolers can learn their letter sounds and formation with this all-new Playfoam set featuring eight colored Playfoam bricks and 13 double-sided letter sound cards. Little learners form their squishy, squashy Playfoam on top of each letter shape, then speak the name of the corresponding object shown on the card to practice the sound each letter makes. Provides tactile and sensory stimulation, helps develop fine motor skills, and teaches proper letter formation
