L7 Compare and Reason about Fractions of a Set

This Year 3 maths resource is a carefully structured lesson designed to help students compare and reason about fractions . Beginning with a recap of prior learning from Year 3 units and the Year 2 summer term, the lesson reinforces the meaning of numerators and denominators and how they affect the size of fractions. Children engage in hands-on activities by drawing counters, circling fractions of sets, and discussing which fractions are greater and why. The lesson progresses to practical exercises where students compare fractions of sets using visual models, counters, and whiteboard drawings , recording their answers with greater than (>) and less than (<) symbols. Through guided discussion and partner work, children develop their reasoning skills and learn to explain their thinking using sentence stems like “_____ is greater than _____ because…”. The plenary encourages active participation and consolidates learning through a true or false activity , reinforcing understanding and addressing common misconceptions such as confusing numerators and denominators, misinterpreting larger denominators, or failing to divide sets into equal parts. Perfect for teachers seeking an engaging, interactive, and concept-focused Year 3 fractions lesson , this resource builds confidence and fluency in comparing fractions while encouraging mathematical discussion and reasoning.
