Chicka Chicka Boom Boom by Bill Martin, Jr. and John Archambault is an excellent book for young readers. This is an excellent way to introduce or review letters and colors. All the letters of the alphabet are written in order and a variety of colors (both primary and secondary) are on every page. I especially like that the book also has a story line to follow so readers don't even notice that the book serves an instructional purpose as well.
I would read this out loud to my class and ask students to say the letter sounds every few pages. I would especially focus on letter sounds that may be difficult for my students to say. In first or second grade I would ask the students to create their own coconut tree and instead of writing letters on them, they could write their sight words.
