Playful Pals Beginning Readers are for kids who are starting to sound out and read words. The repetitive sentence structures and limiting each book to one short vowel enables a gradual and supportive approach to learning to read.I suggest that the child already know their alphabet both capital and lowercase, know the sound each letter makes, and have done a lesson on the particular vowel sound (or word family/blend if appropriate) before jumping into the book.Each book repeats a short sentence and adds extra words each page. Eventually the sentences change completely so there is a sense of plot and story. For example, the first book is "A hat." then "A tan hat." which over many pages results in "A tan hat sat on a rat by a fan." which then changes to other sentences like "A fan taps." and "No nap!"This set includes 10 story books and 40 stickers. There is a parent guide.Level 1 books very carefully control the phonetic sounds so as to not introduce too much at once... however blends do pop up in the text so make sure you teach those sounds before reading the books with blends. I think the Level 1 books should be read in this order: Animal Antics, Playful Pals, Big Fun, and Clever Critters. I think you could intermix them a bit IF you need to (in order to select the right book for the phonic sounds being learned for the week). However, I would not read the books out of order because they are designed to gradually get harder and build upon prior learning. In other words, I could read the first book in Animal Antics and the first two books in Playful Pals then jump back to Animal Antics book 2 - but I would not read book 10 then book 1.
