I wanted to use the Dandelion books with my DS at home to supplement what we're given by school. I like the look of the Dandelion books because of their very systematic approach but not sure whether to go for the Launchers or the Readers. He can read CVC words easily, some HF tricky words and occasional CVCC words. He seems to be doing alright but is not progressing with learning digraphs, which is why I thought these books might help.
