This document provides instruction on measuring capacity using both metric and imperial units. It includes examples of converting between units such as litres and millilitres, kilometres and metres, and imperial equivalents like pints, gallons, and tablespoons. Mental math questions assess conversions between units, and a main activity involves sorting capacity units into metric and imperial categories and answering additional conversion questions.

2. Today we will be learning to:
• use standard metric and imperial units for
measuring capacity
• convert from metric to imperial units
• plot a conversion graph.

3. Mental Activity
We are going metric measures.
You will have 5 seconds to answer
each question

4. How many metres in 1.75km.

5. How many grams in 2.5kg

6. How many kg in 16 000g

7. How many km in 18000m

8. How many litres in 2500ml.

9. How many millilitres in 3.75litres.

10. What is the approximate mass of an apple

11. Main Activity
Today we are going to use metric and
imperial units for measuring capacity.

12. These lines are measured in

186cm
342cm
3.42m
10.8m

14. 1 inch = 2.5 centimetres
1 foot = 30 centimetres
3.3 feet = 1 metre
1 yard = 90 centimetres
1760 yards = 1 mile
1 mile = 1600 metres (1.6km)
Here are the equivalents. They are
approximate.

15. 1 inch = 2.5 centimetres
1 foot = 30 centimetres
3.3 feet = 1 metre
1 yard = 90 centimetres
1760 yards = 1 mile
1 mile = 1600 metres (1.6km)
How many millimetres are there
in 4 inches?

16. 1 inch = 2.5 centimetres

31. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
Here are the equivalents. They are approximate.

32. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
How many pints are there in 4 litres?

33. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
How many gallons are there in 27 litres?

34. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
How many millilitres are there in
8 tablespoons?

35. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
Remember a litre and a quarter is about a
pint and three quaters
Approx 5 litres = 8 pints = 1
gallon

36. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
How many litres in 3 gallons

37. 1 litre = 1.75 pints
4.5 litres = 1 gallon
25 millilitres = 1 tablespoon
What might the conversion graph look like?

38. Group Work
Work in pairs to draw a
conversion graph for 1 gallon
= 4.5 litres. Write six
questions for your graph.
Swap with another pair and
find the answers to their
questions.
