L11 – WWW – Y2 Using the Inverse

Help your Year 2 pupils build fluency and confidence with this interactive Maths Resource Pack, focusing on using the inverse relationship between addition and subtraction. Fully aligned with the National Curriculum, this resource teaches children how to use inverse operations to check their work, solve missing number problems, and explain their reasoning. Through engaging teaching slides and step-by-step worked examples, pupils explore how addition and subtraction are connected. For instance, if they know that 14 – 9 = 5, they can check their answer by working out 5 + 9 = 14. Children are encouraged to use these relationships to verify answers, spot errors, and solve number sentences with missing values. Independent activities give pupils the opportunity to practise applying the inverse in various contexts. Tasks are designed to promote reasoning, self-correction, and systematic problem-solving. Real-life word problems make the learning meaningful, while the plenary helps consolidate strategies and build confidence in checking work.
