Gives a correct explanation with a number x such that 50 ≤ x x as an example, eg:
M6.
•
53 to the nearest hundred is 100, and to the nearest ten is 50 and 2 × 50 = 100
•
50
If it’s 50 or more but less than 55 it will round to 100 (nearest hundred) and
(nearest ten) and 100 is double 50
•
0 is 0 to the nearest 100 and 0 to the nearest 10 and twice 0 is 0
Accept minimally acceptable explanation, eg:
•
51 rounds to 50 and 100
•
54
50 and 54
100
•
50 rounds to 100
•
0 rounds to 0
Do not accept incomplete or incorrect explanation, eg:
•
They used 51
•

•
