Description

Your students can practise their addition and subtraction problem-solving skills using the inverse relationship with these engaging Inverse Two-Digit by One-Digit Add & Subtract Emoji Code Breaker Worksheets.


This hands-on resource combines essential numeracy strategies with a fun decoding challenge that keeps students engaged and motivated. Using the inverse relationship strategy, students will solve two-digit by one-digit addition and subtraction calculations, as well as related word problems. Once they've worked through each problem, they’ll identify specific numbers from their answers to complete an emoji code.


As the final task, students use the descriptions revealed in the code to draw the matching emoji. This fun twist gives students a goal to work towards and helps reinforce the importance of accuracy in problem solving. Designed for differentiation, this resource ensures all students can participate successfully at their own level.
