A-B-A-B-A-a Book of Pattern Play 

In this playful look at patterns, Brian P. Cleary and Brian Gable provide many examples of repeating sequences of shapes, colors, objects, and more. The comical cats of the wildly popular Words Are CATegorical(R) series show how patterns can be found all around us. Peppy rhymes, goofy illustrations, and kid-friendly examples make pattern practice fun!
