The Division Wipe-Off Book
By Scholastic Books.
Description
This wipe-off book makes it easy for you to learn the division tables all by yourself. First, read over the division tables on each page. Then cover up the answers with the wipe-off flap on the back cover. Now you're ready to test yourself. Write the answers on the flap with a grease pencil or erasable felt-tip pen. You can wipe off the flap with a damp cloth & use this book over & over until you get a perfect score. - from Amzon
