## Pour and Fill

### You will need

• Plastic bottles - different shapes and sizes
• Plastic Funnels
• Plastic Jugs

### Directions

• Collect up different size plastic bottles, plastic funnels and jugs for bath-time maths.
• Have fun pouring water into the bottles, whilst playing talk about; Filling the bottle to the top, “Is it nearly full?”, “How many little bottles of water does it take to fill this big bottle?”, “Shall we fill it half full?”.
• You can add some stretch and challenge by marking up quantities with a permanent marker pen or colored waterproof tape. For example, marking up 250ml on a 500ml bottle, and marking up 50 ml units on a 200ml bottle.
• If you have 2 different shaped bottles that hold the same amount ask your child which one he/she thinks will hold the most water. Help him/her test out to see what happens.

### Tips

Playing with water in this way helps children explore capacity and volume.

Talking with your child as they fill up bottles helps them develop understanding of mathematical terms associated with capacity and volume in ways that are meaningful.

Exploring how the volume of water stays the same regardless of the size or shape of a container is an important mathematical concept to develop. This is referred to as conservation of volume; having the ability to understand that redistributing liquid doesnot affect its volume. Children usually master this at around the age of seven years.

Children are likely to think that a tall narrow bottle contains more liquid than an equal amount in a short fat bottle. Through playing with water and different shaped containers that hold the same amount, children will begin to explore conservation of volume.
