These interconnecting Letter Blend Cubes are a fun and affordable alternative to the Movable Alphabets. The set contains ninety cubes in all, consisting of thirty each of green initial blends (bl, sc, wr, etc.), orange medial vowels (ai, oy, ur, etc.) and yellow ending blends (nd, lk, ft, etc.). Each cube measures 2 cm per side and has lower case letters only on two sides (the other two sides are blank). The cubes fit together easily and hold securely once attached, but they are easily pulled apart as well. The set comes with a Teaching Notes & Ideas booklet and is contained in a sturdy plastic jug with a carry handle built into the lid.
