The Letter Construction Activity Set (SKU 93803) gives children the hands-on means to build letter forms from component parts, reinforcing visual discrimination and fine motor precision in a way that complements — rather than duplicates — the Moveable Alphabet and Sandpaper Letters. Designed for use in a visual discrimination or literacy center, it is well suited to early childhood children who need additional tactile reinforcement of letter shape before moving fully into encoding and decoding work. The set is particularly useful for children who are close to reading readiness but need more practice distinguishing visually similar letterforms.
