Length, Mass

and Capacity


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.


Mental Activity

We are going metric measures.

You will have 5 seconds to answer each question









Main Activity

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


These lines are measured in cm what do they measure in mm
These lines are measured in cm. What do they measure in mm?

1.2cm

These things are measured in metres what is the height in centimetres
These things are measured in metres. What is the height in centimetres?

10.8m

1080cm

3.42m

1.86m

342cm

186cm


1 inch = 2.5 centimetres 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.

1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

Here are the equivalents. They are approximate.


1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

How many pints are there in 4 litres?


1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

How many gallons are there in 27 litres?


1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

How many millilitres are there in8 tablespoons?


1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

Approx 5 litres = 8 pints = 1 gallon

Remember a litre and a quarter is about a pint and three quaters


1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

How many litres in 3 gallons


1 litre = 1.75 pints imperial units?

4.5 litres = 1 gallon

25 millilitres = 1 tablespoon

What might the conversion graph look like?


Group Work imperial units?

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.
