That Doesn’t Belong! Doubling & Halving Worksheet is a no-prep, ready-to-use resource that helps students practise doubling, halving, and multiplying by two in an engaging and accessible format. These six worksheets are perfect for reinforcing key number strategies while promoting logical reasoning and critical thinking skills.

Each section of the worksheet presents students with four panels. Three of the panels correctly represent the same number using doubling, halving or multiplying by two, and one panel does not belong. Students must identify which panel is the odd one out by solving the problems and comparing results. This provides an excellent opportunity to strengthen their understanding of basic number operations and develop fluency in mental maths.

This worksheet set is ideal for independent practise, maths rotations, homework, or early finisher tasks. It allows students to work at their own pace while applying learned strategies in a fun and visually engaging way. Best of all - it’s simple to print and go!
