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.
Math primary 3 measurments
- 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
