AABB Pattern with Reptiles and Amphibians

On this sheet the pattern goes first, first, second, second — an AABB pattern — using reptiles like a frog, a snake and a turtle. The child reads the four-part repeat, where each picture comes in a pair, and fills the empty wagons to extend it. Continuing a paired pattern is foundational Kindergarten patterning, the skill of finding and following a rule, with nothing to count.

An AABB pattern travels in twos: a pair of the first picture, then a pair of the second, and around again. A child reads the two-two beat and keeps the blocks coming. Working in pairs — rather than singles — makes a fuller four-beat unit, and a reptiles train keeps the matched blocks easy to see and continue.

Children who read the AABB pattern in pairs get faster at spotting where each block of two begins, and finishing the matched couples feels satisfying, a reward for thinking in twos. When this feels easy, try the pattern in aabb pattern with shapes, or aabb 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 once thinking in twos comes easily, a child is ready for ABC, with its three different pictures in a fixed order — a fresh kind of challenge.
