We have found that lots of children are OK blending 3 sound words but have difficulty blending 4 and 5 sounds words with adjacent consonants (CVCC, CCVC and CCVCC words).
Dandelion Launchers series now has 12 new books which tackle this reading skill. With no more than 10 words of text on each page, and 4 books in each unit, children can really master blending adjacent consonants before moving on.
