Measure the length or a line or object to the nearest centimetre or millimetre.
Draw a line between 6 cm and 7 cm (e.g. 6.2 cm)
Select the most appropriate unit of measurement.
- What unit would you use to measure the length of a ladybug?
- Why would you measure a person's height using both metres and centimetres?
- Why would you use a small unit to measure a large distance?
Expressing lengths using more than one unit e.g. 369 cm = 3 m 69 cm
Changing units of length
How many cm in 45 mm?
How many km in 3800 m?
How many dm in 30 cm?
It is important that you learn the relationship between units: GRADE 4 AND 5
1 cm = 10 mm
1mm = 0.1 cm
1 dm = 10 cm
1 dm = 100 mm
1 cm = 0.1 dm
1mm = 0.01 dm
1 m = 100 cm
1 cm = 0.01 m
1 m= 100 dm
1 dm = 0.1 m
1 m = 1000 mm
1mm = 0.001 m
1 km = 1000 m
1 m = 0.001 km
Word problems (examples)- Chloe is walking to the Superstore a distance of 2 km. So far she has walked 82 000 cm. How many metres does she have left?
