How these activities work
There are 75 tasks across five games, five labs and five thinking sets, plus a separate 20-question quiz. Select a different set without losing your work while this page stays open. Use Reset options to clear one task or its whole set. All cup measurements use the same small-cup unit unless a double-size cup is explicitly introduced.
Jugs and Mugs Class 2 Capacity Notes and Examples
These jugs and mugs worksheets for Class 2 help children measure liquids, compare containers and explain their choices. The online activities focus on capacity rather than mixing length, mass and time into the same practice session. Work with equal cups first, then explore litres, empty space and simple liquid measurement word problems.
What Is Capacity?
Capacity is the maximum amount a container can hold when filled to its intended full level. The amount of liquid inside it now can be smaller. A jug with a capacity of eight equal cups may currently contain only three cups. It can hold five more cups before it is full.
Full Empty Half Full and Nearly Full
An empty container has no liquid inside. A full container has reached its full level. Half full means that half its capacity is occupied. In a straight-sided model holding eight equal cups when full, four cups make it half full. Nearly full means close to the full level; it is a description rather than one fixed fraction for every container.
The level slider uses a straight-sided model, so equal rises represent equal amounts. Real jugs that widen or narrow need a calibrated scale. Do not assume that half the height always means half the capacity in an irregular container.
Measuring Capacity with Cups and Mugs
Choose one cup, fill it to the same level each time and count how many full cups fill a container. Keep the cup size unchanged throughout the comparison. If Jug A holds five cups and Jug B holds seven of the same cups, Jug B has the greater capacity.
A mug is not a fixed unit. Two mugs may hold different amounts. In these activities, “one cup” means one full small measuring cup shown by the task, not a universal household cup size. The double-size cup is defined as exactly two of these small cups.
Why a Bigger Measuring Cup Gives Fewer Pourings
A container holds eight small cups. One large measuring cup holds two small cups. Filling the container requires eight small-cup pours or four large-cup pours. The container’s capacity stays the same.
Changing the measuring unit changes the count. It does not change how much the container can hold. Try the Measuring Cup Switch game and explain the difference between the amount in each pour and the number of pours.
Comparing and Ordering Containers
Use measurements expressed in the same unit. Capacities of three, six and eight equal cups can be ordered from least to greatest as three, six, eight. Greater-than, less-than and equals signs can record the comparison. For example, six cups < eight cups.
Height alone does not prove capacity. A wide short container may hold more than a narrow tall one. Read the labelled measurement or test both with the same cup. The online diagrams are learning models; their labels provide the quantities used in each task.
How Much More Will Fit?
A jug holds nine cups when full and already contains four. Nine minus four equals five, so five more equal cups will fit. Check by adding five to four and reaching nine.
Do not add the capacity and the amount already inside. The capacity is the final full amount, not extra water waiting to be added. The Fill the Free Space lab lets children check the subtraction by pouring.
Sharing Water Equally
Equal sharing means both groups receive the same amount. Eight cups shared equally between two suitable containers gives four cups in each. Start with all eight in one model, transfer one cup at a time and stop when the quantities match.
The total stays eight because nothing is added, spilled or removed. The transfer activities keep track of both containers, helping children check that every cup moved out of one appears in the other.
Litres and Millilitres for Beginners
A litre, written L, and a millilitre, written mL, are standard units used for liquid measurement. One litre equals one thousand millilitres. A milk packet may be labelled in litres and a small medicine measure in millilitres. Read the actual label rather than assuming a value from appearance.
The main games here use small whole-number cup amounts. This lets children investigate capacity before working with larger millilitre calculations. A litre is not the same as a household mug or cup.
Capacity Word Problems with Solutions
A jug contains ten equal cups of juice. Three cups are served. Ten minus three leaves seven cups. The amount inside changes, while the jug’s capacity stays the same.
A bowl can hold six cups and is empty. Seven cups cannot all fit without overflow. Six cups fill it, leaving one cup that needs another container.
Four cups of water and three cups of water make seven cups when poured together without spilling. Check that the receiving container has room for all seven.
Common Capacity Mistakes
Comparing different cup sizes Five small cups and four large cups cannot be compared from the counts alone. First find how much each cup holds.
Confusing capacity with current contents Pouring water out changes the contents, not the container’s maximum capacity.
Guessing only from height A container’s width and shape also matter. Measure or use a trustworthy label.
Ignoring overflow A full container cannot accept another complete cup without liquid spilling. The online controls stop at the stated capacity.
Practical Capacity Activities for Parents and Teachers
- Use cool water, a tray and an adult’s help for real pouring.
- Predict which container holds more, then test with one unchanged measuring cup.
- Mark full and half-full levels on a straight-sided transparent container.
- Count cups aloud and record the result with a drawing.
- Ask what changes when water is moved and what stays the same.
- Use the visible model, optional read-aloud and tap controls in any helpful combination.

Frequently Asked Questions
What do these jugs and mugs worksheets for Class 2 practise?
They practise capacity, full and empty levels, equal-cup measurement, comparing containers, sharing liquids and simple capacity word problems.
What is the difference between capacity and the amount inside?
Capacity is how much a container can hold when full. Its current contents are how much is inside now. An eight-cup jug can contain only three cups.
How do we measure capacity with a mug?
Use the same mug, filled to the same level, for every pour. Count how many full mugfuls fill the container without spilling.
Why must we use the same cup to compare two containers?
Different cup sizes represent different amounts. Using one unchanged cup makes the counts directly comparable.
Does a taller jug always hold more?
No. Width and shape also affect capacity. Use measurements or compare by pouring rather than relying on height.
How do we find how much more liquid will fit?
Subtract the amount already inside from the full capacity, using the same unit for both measurements.
What does half full mean?
The amount inside is half the container’s capacity. In an eight-cup container, four cups make it half full.
Does pouring water into another jug change the total amount?
If nothing is spilled, added or removed, the combined amount stays the same. The amounts in the individual jugs change.
Is every cup equal to one litre?
No. Household cups and mugs vary. A litre is a standard unit. The activities define their small-cup unit and any larger measuring cup explicitly.
How many millilitres are in one litre?
One litre equals one thousand millilitres. The main activities here use small whole-number cup measurements rather than advanced conversions.
Are these activities tied to a particular textbook edition?
They are general Class 2 capacity practice. They are not presented as an exercise-by-exercise answer key for a named textbook edition.
How do the quiz timer and audio work?
The 20-minute timer begins when an answer or quiz navigation is used. Reading aloud alone does not start it. Timer and End Quiz stay inside the quiz section. Audio has a separate Stop Reading button.
