L7 Measure Capacity and Volume (ml/l)

Help Year 3 pupils develop a secure understanding of volume and capacity with this engaging, practical maths lesson. Designed to support the National Curriculum objective of measuring, comparing, adding and subtracting volume and capacity using litres (l) and millilitres (ml), this resource encourages hands-on learning without the need for worksheets. Through a range of interactive activities, children explore the difference between volume and capacity, learn how to read measuring scales accurately, and investigate the relationship between litres and millilitres, including the key conversion that 1,000ml equals 1 litre. Pupils estimate the capacities of everyday containers before measuring them, helping to strengthen both reasoning and practical measurement skills. The lesson includes two collaborative measurement tasks. Children measure the capacity of empty containers by filling them and recording their capacities using measuring jugs, then measure the volume of liquid in partially filled containers. A classroom capacity hunt provides additional opportunities to identify and compare real-life examples of containers with different capacities. Ideal for Year 3 teachers seeking an active and engaging approach to teaching measurement, this resource supports mathematical vocabulary development, estimation skills, accurate scale reading, and a deeper understanding of volume and capacity through practical investigation and discussion. Perfect for classroom teaching, intervention groups, or mastery-based learning approaches, this lesson promotes confidence and fluency in measuring volume and capacity using real-world contexts.
