L2 Use the Formal Written Method to Multiply 3-Digit Numbers by 1-Digit Numbers

This Year 4 Maths lesson planning resource focuses on developing pupils’ understanding of formal written methods for multiplying three-digit numbers by a one-digit number. Designed for the Spring term within the Multiplication and Division unit, this lesson builds directly on prior learning and provides a clear progression from two-digit multiplication. The lesson begins with a structured recap of previous learning, including place value, addition and subtraction, and earlier multiplication methods. Pupils revisit key concepts using place value counters before moving on to more complex three-digit calculations. Visual representations and animated teaching slides support learners in understanding each stage of the formal written method, including the correct order of multiplication and how to exchange (carry) values accurately. Children engage in practical, hands-on activities by selecting and solving multiplication problems collaboratively, recording their methods in maths books. The lesson also includes reasoning and discussion tasks, where pupils analyse worked examples to identify errors and explain their thinking, helping to deepen conceptual understanding and address common misconceptions. With key questions, assessment opportunities, and guidance on potential errors, this resource supports teachers in delivering effective, worksheet-free lessons. Fully aligned with the National Curriculum, it helps pupils develop fluency, accuracy, and confidence in formal multiplication methods.
