L4 Solve Multiplication and Division Missing Number Problems

This comprehensive Year 3 maths lesson focuses on solving missing number problems using multiplication and division, helping pupils develop a secure understanding of inverse operations. Designed as part of the Spring term Multiplication and Division unit, this resource follows a “working without worksheets” approach to promote active learning, discussion, and mathematical reasoning. The lesson begins with a structured recap of prior learning, including multiplication, division, addition, subtraction, and place value. Pupils revisit key facts and explore the inverse relationship between multiplication and division, using this understanding to solve calculations efficiently. Through clear modelling and guided practice, children are introduced to missing number problems and shown how to use inverse operations to find unknown values. Visual supports such as counters and arrays help to reinforce conceptual understanding, making abstract ideas more accessible. Pupils are encouraged to think critically about which operation to use and to explain their reasoning. During independent practice, children solve a range of missing number calculations, recording their methods and answers. Opportunities for discussion and peer collaboration are built into the plenary, allowing pupils to share strategies and reflect on their learning. The resource highlights common misconceptions, such as confusion between operations or difficulty recalling times table facts, and provides opportunities for targeted assessment. Fully aligned with the Year 3 National Curriculum, this lesson supports pupils in developing fluency, reasoning, and problem-solving skills within multiplication and division. Ideal for Key Stage 2 classrooms, maths mastery lessons, or intervention sessions, this resource helps pupils build confidence in tackling missing number problems using efficient strategies.
