Christmas Maths Colour-by-Number Elf | Angle Calculation Worksheet | KS2–KS3 Geometry Activity

Bring festive fun into your Geometry lessons with this Christmas Maths Colour-by-Number Elf activity—ideal for KS2–KS3 pupils practising angle facts and calculation skills. Students work out the size of each angle marked x or y, then use their answers to colour the matching squares on the grid. When completed correctly, the hidden Christmas elf picture is revealed.

On page 1, pupils calculate angles using key angle facts, including angles on a straight line, angles around a point, vertically opposite angles, and supplementary angle rules. The large colour-by-number grid on page 2 uses these (e.g., 30, 51, 53, 77, 110, 140, 303) as colour codes. Page 3 shows the final elf picture for easy marking or modelling.

This activity offers meaningful practice in a calm, seasonal format—perfect for lessons leading up to the Christmas break, revision sessions, early finishers, homework, or cover work.
