Odd One Out

100 worksheets

Odd-one-out worksheets ask a child to look at a small group of pictures and choose the one that does not belong — the animal among the vehicles, the circle among the squares. It is early classification and reasoning: noticing what a set has in common and what breaks the rule, and being able to justify the choice. The tasks are picture-based and suit K-3 with no reading needed. Each odd-one-out worksheet is a free printable PDF with a matching play-online version: the interactive one marks the chosen picture and reveals the answer, the printable suits a centre or homework, and an answer key is included. The full set is available in all 11 languages we publish in.

How to use these worksheets

Print the PDF for a no-prep classroom or homework task, or open the play-online version on a tablet or whiteboard for instant feedback. Every worksheet includes an answer key, so children can self-check or work independently. Mix sheets across themes and grade levels to build a short Odd One Out lesson, or send one home for extra practice.
