2
What unit could we use to measure long distances?

4
1km is slightly more than ½ mile. 1 mile0

5
1km is slightly more than ½ mile. 1 mile0

6
1km is slightly more than ½ mile. 8km is approximately 5 miles 0 0 8km 5 miles

7
1km is slightly more than ½ mile. 8km is approximately 5 miles What is the relationship between 1 mile and 1km? 1 mile =………km1 km = ……miles

8
1 mile =………km1 km = ……miles

9
0 0 8km 5 miles 1 mile =………km1 km = ……miles

10
0 0 8km 5 miles 1 mile =1 km = 8 5 km 5 8 km

11
0 0 5 miles 1 mile =1 km = 8 5 km 5 8 km …but how do we convert these to decimals?

14
1 mile = 1.6 km 1km = 0.625miles

15
Task Place Distance from school: In milesIn km Dogsthorpe (Miss Robson) 5 miles Whittlesey (Mr Morris) 4 miles Lutton (Miss Ryan) 18.3km Bourne (Mrs Cotton) 32.7km Farcet (Miss Fletcher) 2 miles 1 mile = 1.6 km1km = 0.625 miles

17
Extension A Can of cola is about 10 cm high. If the cans were laid end to end, how many cans would be needed to cover a distance of 1 mile?

18
1 can = 10cm 10 cans = 1m 10,000 = 1km 10,000 x 1.6 = ????????????

19
1 can = 10cm 10 cans = 1m 10,000 = 1km 10,000 x 1.6 = 16,000 miles
