6Children and adults enjoy Clare Beaton's fun illustrations while practicing their ABCs with Mudpuppy's on-the-go Animal ABCs Ring Flash Cards. Tip for adults: Each letter of the alphabet is paired with an animal and the back of the cards show the upper- and lowercase letters, as well as other words that start with the featured letter. Ask the child to find a certain letter, or put the cards into alphabetical order. These Animal ABCs Alphabet flash cards were created in association with Barefoot Books.
