L10 Add and Subtract Fractions in Context

Introduce Year 3 pupils to adding and subtracting fractions in context through this engaging and practical maths lesson designed for the Spring Fractions unit. Using real-life problems, visual representations and reasoning activities, children develop confidence in applying fraction skills to meaningful situations. The lesson begins with a recap of prior learning on fractions with the same denominator, including how to add and subtract using numerators and denominators correctly. Pupils then apply this knowledge to contextual problems involving fractions of quantities, ensuring they understand how fractions are used in everyday life. Through clear teaching examples and visual models such as bar models, fraction strips and number lines, pupils learn how to interpret word problems and represent them mathematically. They explore how to decide whether to add or subtract fractions based on the context of the question, reinforcing key problem-solving skills. Children work through practical activities that include word problems, missing number challenges and reasoning tasks that encourage them to explain their thinking using accurate mathematical vocabulary. Guided discussion supports pupils in identifying key information in problems and choosing appropriate strategies. The lesson also addresses common misconceptions, such as misinterpreting the context of a problem or incorrectly applying addition and subtraction procedures. Pupils are encouraged to check their answers and justify their reasoning using visual evidence. Ideal for whole-class teaching, intervention groups and mastery-based maths lessons, this Year 3 fractions resource provides rich opportunities for reasoning, fluency and problem-solving. Fully aligned with the UK National Curriculum, the lesson helps pupils confidently add and subtract fractions in real-world contexts using structured and visual approaches.
