ABB Pattern with Reptiles and Amphibians

On this sheet the pattern goes first, second, second — an ABB pattern — using reptiles like a frog, a snake and a turtle. The child reads the three-part repeat, where the second picture comes twice, and fills the empty wagons to extend it. Continuing a pattern with a doubled trailing element — not a doubled opening one — is foundational Kindergarten patterning, the skill of finding and following the exact rule.

An ABB pattern is the mirror of AAB — here the SECOND picture doubles — so the child must read precisely which element repeats. That close pattern-reading is strong Kindergarten readiness, and a doubled-second reptiles sequence rehearses it while keeping the task about the rhythm, not about numbers.

Children who catch the ABB beat — one picture, then a doubled second — get sharper at noticing exactly which picture repeats, and a finished train is satisfying, proof that patient, close looking really pays off. When this feels easy, try the pattern in abb pattern with shapes, or abb pattern with thanksgiving. You can also browse every pattern worksheet or the whole kindergarten collection — each sheet prints cleanly or plays online for free, and the more doubled-pattern trains a child finishes, the readier they are for longer, four-part patterns that build on these doubled beats, one rung further along.
