L3 Learn the 24-Hour Clock

Support Year 3 pupils in understanding and using the 24-hour clock with this engaging, practical lesson plan. Designed to meet the Year 3 National Curriculum for Time, this resource helps children recognise the relationship between 12-hour and 24-hour time through interactive teaching and hands-on learning rather than worksheets. The lesson begins by revising analogue and digital time before introducing the purpose of the 24-hour clock and where it is commonly used, such as timetables, transport and digital devices. Pupils learn how to convert familiar morning and afternoon times into the 24-hour format, identify patterns in the number system and build confidence in reading and writing times using both formats. Through discussion, practical activities and partner work, children compare 12-hour and 24-hour times, explore real-life examples and apply their understanding in meaningful contexts. Opportunities for assessment, questioning and addressing common misconceptions are included throughout to support all learners. This resource includes: A complete Year 3 lesson plan following the Working Without Worksheets approach Interactive teaching slide guidance Practical activities exploring 12-hour and 24-hour time Starter, introduction, main activity and plenary Key questions to develop mathematical understanding Assessment opportunities and common misconceptions Links to the Year 3 National Curriculum for Time Ideal for classroom teachers, supply teachers, ECTs and home educators, this lesson provides a clear and engaging introduction to the 24-hour clock, helping children develop the confidence to read, write and compare times used in everyday life.
