AAB Pattern with Accessories

An AAB pattern doubles its first picture: one, one, two, one, one, two. This worksheet builds such a pattern with accessories and asks the child to fill the empty wagons by continuing the rhythm. Recognizing that the first element repeats before the second arrives — and predicting the sequence — is patterning beyond simple AB, foundational Kindergarten readiness thinking done by looking, not counting.

AAB is the "lead-doubles" pattern: the opening picture twice, then a different one. Extending it means holding the position of the double in mind — it sits in the first slot — and applying that along the train. With accessories, the front-of-unit repeat stays clear, and a child practises tracking a longer beat than a simple back-and-forth.

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 activities, or aab pattern with bakery treats. 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.
