Last week we revised multiplying and dividing decimals. It’s now time to apply our knowledge with our length conversions. Here are some facts to remember:
1 kilometre = 1000m
To change metres into kilometres we divide by 1000. To change kilometres into metres we multiply by 1000
e.g. 4.5km = 4500m
1 metre = 100cm
To change centimetres into metres we divide by 100. To change metres into centimetres we multiply by 100.
e.g. 3.3m = 330cm
1 centimetre = 10 millimetres
To change millimetres into centimetres we divide by 10. To change centimetres into millimetres we multiply by 10.
e.g. 9.5cm = 95mm
This video will help remind you how to multiply and divide decimals
This video will help you revise how to convert centimetres into millimetres.
(multiplying and dividing by 10 - 1cm = 10mm)
These videos will help you convert centimetres into metres.
(multiplying and dividing by 100 - 1m = 100cm)
These videos will help you convert metres into kilometres.
(multiplying and dividing by 1000 - 1km = 1000m)
We hope you enjoyed the above links.
Your measures booklets are below. Parents - there are two booklets - the second booklet contains more difficult conversions. Please choose the booklet best suited for your child. If you need any guidance on this, please let us know.
The file below contains two maths puzzles.
