Mass and capacity - Compare capacities - Worksheet

The 'Compare Capacity' worksheet is a practical resource for Year 3 students to enhance their understanding of volume and capacity in a measurement context. The National Curriculum objective covered by this lesson is to measure, compare, add, and subtract various units such as lengths (m/cm/mm), mass (kg/g), and volume/capacity (l/ml). Children will utilise differentiated sheets and teaching slides to assist their learning. The key vocabulary for this lesson includes terms like scale, capacity, litres, millilitres, full, and empty. Building on knowledge from Year 2, students will use these terms to make comparisons between different capacities, understanding that litres are typically used for larger amounts and millilitres for smaller amounts. They will practice using inequality symbols to compare the volume of liquids in various containers, with all volumes clearly displayed and written for clarity.

The worksheet encourages reasoning and problem-solving skills, where children are presented with real-world scenarios involving different containers of water. They are tasked with determining who has the most water by using comparison symbols such as less than (<), greater than (>), and equal to (=). For example, they will compare the total volume of water in multiple containers, such as 500 ml bottles, against a single bottle containing 1 litre, and use their calculations to prove their answers. The worksheet provides an excellent opportunity for students to apply their knowledge of measurement and develop their mathematical reasoning by engaging with questions that require them to compare, calculate, and convert measurements between litres and millilitres.
