L8 Find Non-Unit Fractions of Quantities

This Year 4 fractions lesson focuses on finding non-unit fractions of quantities using a practical, worksheet-free approach that builds on pupils’ prior understanding of unit fractions. Designed for the Autumn term, this lesson is fully aligned with the KS2 National Curriculum objective: solving problems involving increasingly harder fractions to calculate quantities. The lesson begins by revisiting the definition of a non-unit fraction (a fraction with a numerator greater than 1) and explicitly explores the roles of the numerator and denominator. Using bar models, sticky dots, and concrete representations, children learn to find non-unit fractions of quantities by dividing by the denominator and then multiplying by the numerator. Through structured questioning and visual modelling, pupils deepen their understanding that non-unit fractions cannot be compared in the same way as unit fractions, and that both the numerator and denominator affect the size of the fraction. Children record their learning by cutting, sticking, and annotating bar models in their maths books, supporting accurate calculation and reasoning. This lesson includes key questions, assessment opportunities, and common misconceptions to support effective teaching and help identify gaps in understanding. Animated teaching slides provide clear modelling and whole-class discussion, making this an engaging and accessible lesson for all learners. Includes: Detailed lesson plan (Working Without Worksheets) Clear focus on finding non-unit fractions of quantities Practical bar model activities using concrete and pictorial representations Key questions to support reasoning and discussion Assessment opportunities and common misconceptions Fully aligned with the Year 4 fractions curriculum
