The Read Write Inc. Phonics Sound Blending Books provide extra practice for those children who are beginning to blend confidently. The Sound Blending Books are simple, one-word-per-page books for individual or partner practice. Each word is first encountered on the right-hand page. When the child turns the page, they will see the word again, with any digraphs ('special friends') underlined and an accompanying picture, so they can check they have read the word correctly. There are ten books, progressing in complexity from simple CVC words, to CVC words with digraphs, to CVCC/CCVC words and beyond. The books should be used after children can confidently blend with Nursery Green Word Cards, and before children read the Red Ditty Books. - from Amzon
