Units Of Capacity Practice Activities
Printable Class 3 maths worksheets for practising units of capacity, choosing litres or millilitres, comparing quantities, and solving simple capacity questions.
Practice that builds confidence
What children learn about capacity
These Class 3 Mathematics worksheets help children understand capacity as the amount a container can hold. Learners practise using litres and millilitres, choosing a sensible unit, comparing capacities, and reading everyday measurement situations.
The printable activities include clear questions with familiar containers such as bottles, buckets, cups, and medicine spoons. Children move from identifying units to applying capacity ideas in short word problems and measurement-based reasoning.
Capacity is a practical measurement idea: how much liquid a container can hold. In Class 3, children usually meet litres for larger amounts and millilitres for smaller amounts. These worksheets build the vocabulary of full, empty, more, less, litre, millilitre, container, and capacity through written practice.
From real containers to written maths
The practice progresses from recognising suitable units to comparing two or more quantities. A child may decide that a water tank is measured in litres, while cough syrup is measured in millilitres. Questions may also ask learners to order capacities, complete simple statements, or solve short problems based on pouring, buying, or using liquids.
A concrete parent routine
At home, keep one 1-litre bottle, a small cup, and a labelled medicine spoon or measuring cap nearby. Before starting a worksheet, ask: “Which one holds more?” and “Would we use L or mL?” Then let the child answer a few questions, pause to explain their thinking aloud, and check whether the chosen unit matches the size of the object.
Classroom uses for teachers
Teachers can use these pages after a hands-on measurement lesson, as maths notebook practice, or as a quick check during a Measurement unit. They also work well in small groups: one group can sort examples into litres and millilitres, while another solves comparison and word-problem questions. The printables give useful evidence of who understands the unit, not just the number.
Common errors to watch for
Many children write the larger number without checking the unit, so 750 mL may be treated as more than 2 L. Some also use litres for tiny quantities or millilitres for large containers. Encourage children to look at both parts of a measure: the number and the unit. If conversion is included, remind them that 1 litre equals 1000 millilitres.

Why iBloom worksheets help
iBloom worksheets keep the focus narrow and age-appropriate for Class 3 Measurement. The examples are familiar, the layout is uncluttered, and the questions encourage children to connect maths with daily life. A helpful child-friendly strategy is: “Think of the container first, then choose the unit.”
Helpful answers
Frequently asked questions
What do Class 3 children practise in units of capacity?
They practise understanding how much a container can hold, using litres and millilitres, choosing the correct unit, comparing capacities, and answering simple capacity-based questions.
Should my child know both litres and millilitres before using these worksheets?
A basic introduction helps, but the worksheets also reinforce the difference. Children can use examples such as a water bottle for litres and a medicine spoon for millilitres.
How can I explain litres and millilitres at home?
Show a 1-litre bottle and a small measuring cap or spoon. Explain that litres are used for bigger amounts of liquid, while millilitres are used for smaller amounts.
Do these worksheets include word problems on capacity?
Yes, the practice can include simple real-life questions involving containers, pouring, buying liquids, or comparing how much different containers hold.
What common mistake should I watch for in capacity questions?
Children often compare only the number and ignore the unit. Remind them to check whether the quantity is in litres or millilitres before deciding which is more or less.
Is this class 3 units of capacity worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this class 3 units of capacity worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this class 3 units of capacity worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
