The Bjorkman kids loved these and so did Mom. Levels K-C focus on intensive and systematic phonics integrated with spelling. Each picture clue is a beautiful 4-color photograph, and every skill is introduced in context to teach students to apply phonics to real reading.
Level A is recommended for 1st grade. Use your judgment based on your child's ability to begin decoding words. It will be assumed that they know their letters and corresponding sounds.
