This is an example for a class book.
I made this one, you can use for a template.
You take your class list, and plug each child's name in on the page where they have a letter. I put the letter on that page in red to make it stand out. Example, on the "A" page, Ariana has 3 A's in her name, and all 3 are in red.
This is created in a Word document for you to easily change the names in your class list.
You can also use this as a master list if you teach "Letter of the Week"- use the kids names and put in a pocket chart.
I have also brought this up on my Promethean Board (Smart Board) if printing is not an option.
