Reading a ruler: a step further
124 The ribbon starts at 0 and ends 4 past the 20: 24.
217 The string starts at 0 and ends 2 past the 15: 17.
38 Count the spaces from 3 to 11: 8. Or take away: 11 - 3 = 8.
412 Count the spaces from 6 to 18: 12. Or take away: 18 - 6 = 12.
5pencil B A is 7 cm. B starts at 1 and ends at 9, so it is 8 cm. C starts at 4 and ends at 10, so it is 6 cm. B is the longest.
62 B is 8 cm and C is 6 cm. 8 - 6 = 2.
76 The twig is 9 cm and the stick is 15 cm. 15 - 9 = 6.
8False It starts at 5, not at zero. From 5 to 20 is 15 spaces, so it is 15 cm long.
921 − 6 Take the start from the end: 21 take away 6 is 15.
101-B, 2-A, 3-C Count the spaces from where it starts to where it ends.
112, 1, 3 The first is 5, the second is 6 and the third is 8.
