Dogs In Coats is a dog-lovers delight. The joy of seeing 400 dogs in various dog park settings adds to the fun of learning to count and add. Children age 3 and older will find an equation on each page to verify the sum of dogs in coats and without coats. Every dog is someone's pet with their name beside each photo. The colorful backgrounds by Illustrator, Jenn Sargent shows dog owners at the top of each page from the dog's point of reference. This is a wonderful way to encourage memorizing mathematical facts.
