When beginning readers recognize these word families, it increases their reading fluency and comprehension skills and makes them happier readers.

Your children can read the e-books and listen to the audio books at the same time to increase their enjoyment, fluency, and independence. Mark D. Pencil and Friends are popular children's musicians.
