Working Without Worksheets – Year 1 Fractions: Recognising a Quarter of a Quantity Help your Year 1 pupils understand fractions in context with this Working Without Worksheets lesson, where children learn to recognise a quarter of a quantity as 1 of 4 equal groups. Instead of worksheets, pupils use practical resources, group discussions, and independent recording in their maths books to secure their understanding of quarters. The lesson begins with a recap starter, including: Solving a simple subtraction word problem Practising number formation Drawing lines to split shapes into quarters The starter game is Spot the Difference, where children compare sets of counters and identify whether groups are equal or unequal. Teacher modelling then demonstrates sharing quantities into 4 equal groups (e.g. 8 counters → 4 groups of 2 ), showing how to check if the groups are equal. Pupils practise recognising whether examples show quarters and recording sentences such as “2 is a quarter of 8” in their maths books. The independent detective activity makes learning active: Children walk around the classroom looking at sorting hoops filled with counters. They decide if the counters are split into 4 equal groups or not. In their maths books, they note the group number and mark ✔ or ✘ to show if it represents quarters. If it does, they record a sentence (e.g. 3 is a quarter of 12 ). The plenary uses a reasoning problem: “Tia has 9 teddies. She shared them between 4 friends. Did she make quarters?” Pupils discuss why 9 cannot be shared equally into 4 groups, reinforcing the importance of equal parts. What’s Included in the Pack? ✔ Full teacher planning with objectives, modelling, and plenary guidance ✔ Recap: subtraction problem, number formation, and splitting shapes into quarters ✔ Vocabulary focus: quarter, equal, unequal, part, whole, share, group ✔ Starter: Spot the Difference – equal vs unequal groups with counters ✔ Practical task: share quantities into 4 equal groups to re
