ABB Pattern with Dinosaurs

What comes next when the second picture doubles? This ABB pattern worksheet sets up a three-picture unit with dinosaurs — the first once, the second twice — and the child continues it down the train. Working out a pattern where the trailing element repeats is deeper pattern-recognition, and telling it apart from a first-doubled (AAB) pattern sharpens a child's eye for the exact rule. The familiar a T. rex, a stegosaurus and a raptor keep the focus on the doubling.

Extending an ABB pattern means recognizing that the trailing element repeats and applying that across the wagons. For a Kindergarten child it builds careful pattern-awareness with familiar dinosaurs, keeping the focus on the doubled-second rhythm and on telling it apart from its mirror.

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 easter, or abb pattern with forest creatures. 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.
