About this resource

Help your Year 4 class develop a secure understanding of perimeter with this engaging, worksheet-free lesson on measuring and calculating the perimeter of rectilinear shapes. Created for the Year 4 Spring Measurement unit, this interactive resource introduces pupils to the concept of perimeter as the total distance around a shape before guiding them through measuring and calculating the perimeter of rectilinear figures in centimetres. Through clear teacher modelling, animated teaching slides and practical, hands-on activities, children learn efficient strategies for adding side lengths and solving perimeter problems, including those with missing measurements. The lesson begins with a recap of units of length and accurate measuring using rulers before introducing rectilinear shapes and the meaning of perimeter. Pupils explore different calculation strategies, such as adding pairs of equal sides first, before applying their understanding by constructing their own rectilinear shapes using cubes, measuring each side and calculating the perimeter. The lesson finishes with reasoning tasks that encourage children to explain their methods and solve increasingly challenging perimeter problems. Ideal for teachers looking for an interactive alternative to traditional worksheets, this resource promotes active learning while supporting mathematical reasoning, problem-solving and fluency. This resource includes: Complete Year 4 lesson planning Interactive teaching slides with animations Practical worksheet-free learning activities Hands-on perimeter investigations using cubes Measuring activities using rulers Fluency, reasoning and problem-solving tasks Key assessment questions Common misconceptions and teaching guidance Curriculum Coverage: Year 4 Measurement Measure and calculate the perimeter of rectilinear figures Calculate perimeter in centimetres Find missing side lengths Develop measuring accuracy using rulers Strengthen mathematical reasoning and problem-solving skills PeRead more
