Action Factor's Alphabet Books build letter identification skills by calling attention to the shapes of letters. In Alphabet Letters, capital letters are likened to common objects. In Little Partners, lower-case letters are broken down into component parts. Read-and-Sing characters Amos, Eli, Ivy, Otis, Uri, and Yvette keep children's attention on the letter shapes as they point to features in the illustrations and join in the lively songs. All Read-and-Sing Books include sing-along CDs with two tracks--one vocal and one instrumental. After a bit of practice with the vocal track, children can perform the alphabet songs using just the instrumental track. The inside back cover of each book contains activity suggestions for reinforcing the alphabet letters, with ideas for before, during, and after reading the books.
