This block helps pupils build secure understanding of length and perimeter through practical measurement and problem solving. Pupils begin by measuring and comparing lengths in metres and kilometres, and finding equivalent distances using place value strategies. They then apply this understanding to calculating perimeter in a range of contexts.
In the second week, pupils extend their learning to finding missing lengths and calculating the perimeter of shapes, including rectilinear shapes and polygons. Visual models, labelled diagrams and structured representations support learners to choose appropriate strategies and build fluency with both addition and subtraction in measurement contexts.
Every lesson pack includes differentiated worksheets, teaching slides and detailed planning aligned with the White Rose small steps, supporting fluency, reasoning and problem-solving throughout the unit.
Our Year 4 length and perimeter resources guide pupils from foundational measurement through to calculating perimeter in varied contexts. Pupils learn how to measure and compare distances, recognise equivalent lengths, and apply addition and subtraction when calculating perimeter.
The block includes tasks that reinforce place value in measurement and build confidence in solving perimeter problems with missing dimensions and irregular shapes. Each lesson pack is designed to strengthen conceptual understanding while building accuracy and reasoning in problem solving.
If you’re following the White Rose Maths scheme, our Year 4 length and perimeter resources cover everything needed for Spring Block 2. These engaging and differentiated lesson packs support whole-class teaching while helping pupils to build lasting confidence with measurement and perimeter.
