## Lesson 8 - Comparing Capacities

To encourage your child to have fun on the Web while learning about Comparing Capacities, here are some games and interactive activities they can do on their own or in pairs.

### Instructions for Use

Can you fill it? lets your child estimate the amounts containers can hold.

To use Can you fill it?, click on the pot to fill the containers with water. There is a choice of three different size pots. Using the fewest combinations of pots, fill the container without letting it spill over.

Measuring Cylinder prompts your child to estimate and measure the capacity of virtual liquids by turning the tap on, or turning the drain tap.

To change the value of the scale, click the 'Maximum' buttons up or down. To change the scale interval, click the 'Interval' buttons up or down. Click the control panel on the tap to set the amount of liquid to add to the cylinder, or click the tap to add liquid.
