This is Bob Books bestselling first reader, introduced more than 35 years ago and used by millions of children. If your child knows the alphabet, Bob Books Set 1 is the book to start him or her on the path to reading.Many early readers contain words that are too difficult for a child who has just learned the sounds of the alphabet. Not these books! Using only the letters M, A, T and S, children can read their first book. New letters are added gradually, until all letters of the alphabet have been introduced (except Q). Short vowels and three-letter words in simple sentences help kids build reading confidence. They love the stories and funny pictures, and can't wait to read them to everybody they know.
