What fun! This book is a great read-aloud. Each two-page spread focuses on a color. The first half of the rhyme deals mostly with nouns associated with Halloween of the particular color while the second half of the rhyme gives a wonderful list of adjectives that describe the color. For example, my favorite is the very first one:
Slimy-grimy, queasy-peasy, snotty-rotty
Tinge of green.
Shivery Shades of Halloween is perfect for classrooms and libraries. Use it for color reinforcement for the little ones and maybe a writing center for the older kids.
