The document provides information and examples on measuring length using different units including metres, centimetres, millimetres, and kilometres. It shows how to convert between units and compares/orders lengths. Examples are given for converting between m and cm, cm and mm, and km and m. Lengths are arranged from shortest to longest and written in different unit forms.

1. MEASURMENTS
Length in metres (m) and centimetres (cm)
10 20 30 40 60 70 80 90
50 cm 150 cm 250 cm
0m 1m 2m 3m
1 m = 100 cm 100 cm = 1 m
2 m = 200 cm 300 cm = 3 m
150 cm = 1 m 50 cm 250 cm = 2 m 50 cm

2. Convert metres to centimetres
1. 1 m 20 cm =1m + 20 cm
= 100 cm + 20 cm
= 120 cm
2. 2 m 5 cm =2m + 5 cm
= 200 cm + 5 cm
= 205 cm
3. 3 m 63 cm = 3 m + 63 cm
= 300 cm + 63 cm
= 363 cm

3. Convert metres to centimetres
1. 180 cm = 100 cm + 80 cm
=1m + 80 cm
= 1 m 80 cm
2. 265 cm = 200 cm + 65 cm
=2m + 65 cm
= 2 m 65 cm
3. 505 cm = 500 cm + 5 cm
=5m + 5 cm
= 5 m 5 cm

4. Compare and order length m and cm
Circle the longest lengths
1. 2 m 24 cm , 214 cm
2. 102 cm , 1 m 20 cm
3. 2 m 4 cm , 240 cm
4. 3m , 294 cm
5. 5 m 50 cm , 505 cm
6. 630 cm , 3 m 60 cm
7. 1 m 10 cm , 10 m

5. Compare and order length m and cm
Arrange the lengths in order begining from the shortest
1. 2 m 30 cm , 203 cm , 1 m 3 cm
1 m 3 cm , 203 cm , 2 m 30 cm
2. 190 cm , 1 m 19 cm , 9m
1 m 19 cm , 190 cm , 9m
3. 245 cm , 425 cm , 2 m 54 cm
245 cm , 2 m 54 cm , 425 cm
4. 30 cm , 3m , 1 m 3 cm
30 cm , 1 m 3 cm ,3m
5. 10 m , 110 cm , 1 m 1 cm
1m 1 cm , 110 cm , 10 m

6. Lenght in centimetres (cm) and millimetres (mm)
1 2 3 4 6 7 8 9
5 mm 15 mm 25 mm
0 cm 1 cm 2 cm 3 cm
1 cm = 10 mm 10 mm = 1 cm
2 cm = 20 cm 30 mm = 3 cm
15 mm = 1 cm 5 mm 25 mm = 2 cm 5mm

7. 0 cm 1 cm 2 cm 3 cm 4 cm 5 cm 6 cm 7 cm
5 cm 5 mm
3 cm
4 cm 3 mm
5 cm 9 mm
7 mm

8. Convert centimetres to millimetres
1. 1 cm 5 mm = 1 cm + 5 mm
= 10 mm + 5 mm
= 15 mm
2. 2 cm 1 mm = 2 cm + 1 mm
= 20 mm + 1 mm
= 21 mm
3. 5 cm 3 mm = 5 cm + 3 mm
= 50 mm + 3 mm
= 53 mm

9. Convert centimetres to millimetres
1. 18 mm = 10 mm + 8 mm
= 1 cm + 8 mm
= 1 cm 8 mm
2. 26 mm = 20 mm + 6 mm
= 2 cm + 6 mm
= 2 cm 6 mm
3. 55 mm = 50 mm + 5 mm
= 5 cm + 5 mm
= 5 cm 5 mm

10. Lenght in kilometres (km) and metres (m)
1 kilometres = 1000 metres
1 km = 1000 m
1. 2 km = 2000 m
2. 6 km = 6000 m
3. 1 km 200 m = 1 km + 200 m
= 1000 m + 200 m
= 1200 m
4. 3 km 150 m = 3 km + 150 m
= 3000 m + 150 m
= 3150 m

11. Write in metres
1. 4 km 25 m = 4 km + 25 m
= 4000 m + 25 m
= 4025 m
2. 5 km 5 m = 5 km +5m
= 5000 m + 5 m
= 5005 m
3. 1 km 125 m = 1 km + 125 m
= 1000 m + 125 m
= 1125 m

12. Write in kilometres and metres
1. 3500 m = 3000 m + 500 m
= 3 km + 500 m
= 3 km 500 m
2. 1250 m = 1000 m + 250 m
= 1 km + 250 m
= 1 km 250 m
3. 4444 m = 4000 m + 444 m
= 4 km + 444 m
= 4 km 444 m

13. Write in kilometres and metres
1. 2012 m = 2000 m + 12 m
= 2 km + 12 m
= 2 km 12 m
2. 6050 m = 6000 m + 50 m
= 6 km + 50 m
= 6 km 50 m
3. 7005 m = 7000 m + 5 m
= 7 km +5m
= 7 km 5 m
