Rainbow book.  Our book is made from 1/2 sheet of regular paper.  On the colored cover (any color acceptable) is a crayon with the word colors on it.  Inside are pages for red, yellow, orange, blue, green, purple, brown, and black.  On the red page, at bottom, is a 1/2 inch color dot and the color word handwritten in color.  Teacher has precut the 9 colors of crayons and children match and glue.  Or if time permits you could let child cut out one or two, and have the rest precut.
