4 sets of photographic images representing words featuring consonant blends (th, sh, ch, ing) and only short vowel sounds, with control cards for spelling. There are six words in each set. Photographs refer to Montessori works, such as images of the brown stair to represent the words "thick" and "thin".
These cards are intended to be used with a Moveable Alphabet (not included). The child lays out the picture cards, uses the moveable alphabet to sound out the words phonetically, and then checks and corrects their own spelling using the control cards.
The cards are color-coded blue for consonant blend spelling. (See "Pink Series" for simple CVC spelling and "Green Series" for long vowel patterns).
See Blue Series Set A for simple consonant blends (st, pl, tr, etc.)
