I love these books to help my son learn to read. He’s 6 and this level has been the most “challenging” which is perfect. The pictures help but do not exactly match the words like in level A and B. So he actually has to focus more on the words. I really believe these books have helped reinforce reading at home. The stories are a little meh. It it’s only 8 pages and he can feel a sense of accomplishment after completing a book.
