KS2 Maths Dingbats Codebreaker | Addition and Subtraction Worksheets with Answers

This Emoji Code-Breaking Activity Pack is a fun and engaging way to help learners practise addition and subtraction while developing problem-solving skills. Suitable for KS2, lower KS3, intervention groups, and SEND support, these worksheets combine arithmetic practice with an enjoyable code-breaking challenge.

Students use the emoji key to solve each calculation and reveal numbers needed to complete a final code.
