How to practice: The most important thing to do is to point out patterns that you see in your world to your child, and then to practice patterning with things you have at home. “Body patterning” is also a fun way to practice, such as touching your head, then shoulders, head, then shoulders, etc. I always teach the patterning songs from HeidiSongs’ Musical Math CD/DVD to help children learn to identify and name the AB, ABC, and AAB patterns.
