Why does Part 2 use a different letter system than Part 1?

Research shows that involving multiple senses helps children gain a deeper understanding of what they’re learning. That’s why this programme teaches your child through a hands-on approach. In Part 1, they can feel the shape of each as they work on individual letter sounds. In Part 2, they’ll use the Wooden Letter Sound Tiles to explore concepts like consonant digraphs (when two consonants represent one sound).
