L3 Multiply Quantities to Scale Up or Scale Down

Description

This Year 4 Maths lesson planning resource focuses on solving scaling problems within the Multiplication and Division unit for the Spring term. Designed to build pupils’ problem-solving and reasoning skills, this lesson helps children understand how quantities can be increased or decreased using multiplication and division.

The lesson begins with a recap of prior learning, including multiplication and division facts, as well as place value and calculation strategies. Pupils engage in reasoning activities such as identifying true or false number sentences and solving missing number problems, helping to strengthen their mathematical understanding before moving on to scaling.

Using visual representations such as bar models, the lesson introduces scaling in a clear and accessible way. Pupils explore a range of real-life word problems, including multi-step questions, and are encouraged to identify the correct operations needed to solve them. Interactive teaching slides with animations support modelling and explanation, while practical activities—such as sticker-based word problems—allow pupils to apply their learning independently.

The lesson also promotes mathematical discussion and reasoning, with opportunities for pupils to explain their methods, compare strategies, and justify their answers. Key questions, assessment opportunities, and common misconceptions are included to support effective teaching and ensure progression.

Aligned with the National Curriculum, this resource covers integer scaling, correspondence problems, and the application of multiplication and addition, making it ideal for developing fluency and confidence in solving word problems.
