WALT: measure in litres (l).
Capacity is the amount of liquid a container can hold.
Volume is how much liquid is in the container.
We can measure both in millilitres and litres.
Measuring in litres
A litre is much more than a millilitre.
1 litre = 1000 millilitres
We shorten litre to ‘l’, so we might also say:
1 l = 1000 ml
We use litres to measure larger capacities, for example:
how much water you might drink in a day.
how much paint is needed to paint a room.
WALT: measure temperature (°C).
Visist https://www.bbc.co.uk/bitesize/articles/zfvfxbk and watch the videos. In the first video, you will learn about the unit of temperature, degrees Celsius (°C). You will read some thermometers and think about what each temperature feels like. In the second video, you will practise reading different thermometers. You will also think about how you can compare different temperatures.
- The greater the temperature, the warmer it is.
- The smaller the temperature, the cooler it is.
WALT: tell the time (o'clock and half past).
When the minute hand on a clock is pointing to 12, we say it is o'clock. When the minute hand points to 6, we say it is half past. Can you read the time on this clock?
On this clock above the minute hand is pointing to 12, so it is 'o'clock'. The hour hand points to 3, so it is 3 o'clock. What is the time on this clock?
On this clock, the minute hand points to 6 so it is ‘half-past’. The hour hand points halfway past 8 so it is ‘half past 8’.
WALT: tell the time (quarter to and past).
When the minute hand is pointing to 3, we say it is a quarter past.
When the minute hand points to 9, we say it is a quarter to.
Follow the slideshow below to find out more. There are some questions at the end for you to try.
WALT: tell the time (to 5 minutes).
When the minute hand on a clock moves from one number to the next, it has moved 5 minutes.
There are 12 numbers around the clock face, and each interval is 5 minutes, so there are 12 × 5 = 60 minutes in an hour.
Let's use this knowledge to tell the time on the clocks below.
Check the minute hand to see if it shows minutes past or minutes to the hour.
