The big-and-small comparison sheets on this page train the first logical operation children master: comparing along a dimension. Which is bigger? Which is smaller? With familiar pictures at two sizes, children make a judgment, explain it, and move on — dozens of times per sheet.
Size comparison sounds simple, but it is the root of ordering, measuring, and eventually number comparison. Print the free PDFs or use the tap-to-answer browser version; both give young children a satisfying run of right answers that builds reasoning confidence.

Frequently asked questions
- Why is comparing sizes considered logic?
- Because it's a judgment along a rule — 'bigger than' — applied consistently. Holding a rule steady across many examples is the core of logical thinking, and size is the dimension three-to-five-year-olds grasp first.
- What language should I use alongside these sheets?
- Say the full comparison out loud: 'the elephant is bigger than the mouse.' The comparative sentence pattern is as valuable as the visual judgment itself.
- Is the online version suitable for a three-year-old?
- Generally yes with an adult nearby — the tasks are tap-only and self-checking. For the youngest children, the printed version plus talking together tends to work even better.
