This math worksheet helps children learn about capacity by asking them to select the container with the greatest volume in each set.

To solve this task, we need to look at each row of containers and decide which one can hold the most liquid. "Capacity" means how much space is inside a container for holding things like water or juice.

Here is the step-by-step thinking for each row:

Row 1:
- Egg cup: Very small, holds just one egg or a tiny bit of liquid.
- Mug: Holds a drink, like tea or coffee. It’s bigger than an egg cup.
- Teacup: Similar to a mug but usually a bit smaller and shallower.
- Winner: The mug is typically the largest of these three for holding liquid.

Row 2:
- Barrel: A large wooden or metal container, often used for storing lots of liquids (like oil or wine).
- Baby’s bottle: Holds about 8–10 ounces of milk. Small.
- Bucket: Holds a few liters of water, but much less than a barrel.
- Winner: The barrel is by far the biggest.

Row 3:
- Saucepan: Used for cooking, holds maybe 1–2 liters.
- Can of cola: Standard size is 330 ml or 12 oz — quite small.
- Paddling pool: A small inflatable pool for kids. Even a small one holds many liters of water — much more than a saucepan or soda can.
- Winner: The paddling pool holds the most.

Row 4:
- Juice carton: Usually 1 liter or less.
- Tin of paint: Paint tins are often 1 gallon (~3.8 liters) or 5 liters — quite big.
- Spray bottle: Holds maybe 500 ml to 1 liter — smaller than a paint tin.
- Winner: The tin of paint usually has the largest capacity.

Let me double-check:
- Mug > teacup > egg cup → ✔ mug
- Barrel >> bucket > baby bottle → ✔ barrel
- Paddling pool >> saucepan > cola can → ✔ paddling pool
- Tin of paint (often 5L) > juice carton (1L) > spray bottle (≤1L) → ✔ tin of paint

All choices make sense based on everyday experience.

Final Answer:
mug, barrel, paddling pool, tin of paint
