all the way through! books 1-8 and 1/2 books are just so wonderful! all my boys enjoy these books and there just so simple yet get the job done right! the a,b,c books are fantastic at teaching letter sounds and letter writing practice. it taught my 4 year old son all his letter sounds and it stuck too with only 2-4 simple pages a day and great price. we have used this program all the way through and have no complaints! great on its own or just extra practice.
I bought this for students in my ESE program who are more than 2 years behind in phonemic awareness. They have made continual progress beginning with Book A to B and now C. The repetition allows them to build schema through the pictures and thus helps them make connections with the sounds. I am very pleased with this series.
My almost four year old daughter has loved doing the Get Ready, Get Set, and Go for the Code workbooks. It has really helped her with writing her letters and she loved all the activities in each section. I am definitely glad that we started at this level for her as it has given her such a great sense of accomplishment to have simple activities to do while working on her letter writing and sounds.
