L10 Subtract Fractions with the Same Denominator

This Year 4 fractions lesson focuses on subtracting fractions with the same denominator using clear visual representations and a practical, worksheet-free approach. Designed for the Autumn term, the lesson is fully aligned with the KS2 National Curriculum objective: add and subtract fractions with the same denominator. The lesson begins by linking fraction subtraction to subtraction of whole numbers, using familiar representations such as ten frames to activate prior learning. Children then move on to subtracting fractions using bar models, pizza models, and pictorial representations, helping them see that subtracting fractions means removing equal parts from a whole. Through teacher modelling and guided discussion, pupils learn that when subtracting fractions with the same denominator, the denominator stays the same and only the numerators change. Children explore examples where zero parts are subtracted, as well as more challenging representations where multiple parts are crossed out together. Pupils record their learning through cut-and-stick activities, writing the corresponding subtraction calculations and answers. A carefully structured plenary challenges children to identify correct and incorrect calculations, including an introduction to equivalent fractions (e.g. recognising that 5/10 is equivalent to 1/2). This lesson includes key teaching points, assessment opportunities, and common misconceptions to support secure understanding and effective formative assessment. Includes: Detailed lesson plan (Working Without Worksheets) Practical activities for subtracting fractions with the same denominator Visual models including bar models, ten frames, and real-life contexts Cut-and-stick fraction representations Reasoning opportunities and common misconceptions Fully aligned with the Year 4 fractions curriculum
