AAB Pattern with Musical Instruments

In an AAB pattern, the first picture comes twice before the second — and that is the rule the child extends on this sheet of instruments. The pattern repeats in threes (picture-one, picture-one, picture-two), and the child completes the blank wagons by keeping the doubling going. Recognizing that the first element repeats before the second changes is patterning a level beyond AB, the kind of rule-finding Kindergarten readiness is built on.

The signature of an AAB pattern is the doubled lead: picture-one says itself twice, then picture-two answers once. A child extends it by predicting when the lead returns and when the second finally arrives. That listen-for-the-beat thinking, set on a instruments train, is the natural next rung after a plain alternating pattern.

Children who can hear the AAB beat — the lead picture twice, then one — get quicker at front-loaded patterns, and cracking the front-loaded rhythm feels good and earns a careful ear its reward. When this feels easy, try the pattern in aab pattern with community helpers, or aab pattern with reptiles and amphibians. You can also browse every pattern worksheet or the whole kindergarten collection — each sheet prints cleanly or plays online for free, and once the doubled-lead beat is easy, a child is ready for ABB, where it is the second picture that doubles instead — the mirror image of this one.
