M1.2
! Money
2
or
Shows the digits 15(…) or 16 as evidence of a
correct method (correct value but not correctly
rounded to the nearest penny), eg:
•        1.5(…)
Do not accept Do not accept 150 as showing
digits 15(…)
(restates value from question)

OR
Shows or implies a complete correct method, eg:
•        £33.50 ÷ 150 = 0.22
0.22 ÷ 14
•        150 × 14 = 2100
£33.50 ÷ 2100
! Inconsistent conversions
Within an otherwise correct method condone
inconsistent conversions between pence and pounds

OR
Shows a method for evaluating the cost of the labels at 1p and 2p each, eg:
•        14 × 150 = 2100
2 × 2100 = £42
1 × 2100 = £21

M2.2.2
! For 1m, accept 2.1
(correct value but not correctly rounded)
2
or
10.648 or 10.65 or 10.6 seen (the answer to 2.2 × 2.2 × 2.2)
OR
2.15(…) seen

OR
Shows a correct method using trial and improvement, eg:
•        2 × 2 × 2 = 8
2.5 × 2.5 × 2.5 = 15.625
2.1 × 2.1 × 2.1 = 9.261
•        2.4 because it’s bigger than 2.1 which was too
small, but smaller than 2.5 which was too big
! Trial and improvement methods

There must be at least three trials. At least three
of these trials must reduce the interval in which
the solution is known to lie
and
at least two trials must use values to 1 decimal place
! Numbers not evaluated within trial and
improvement methods
Condone methods that do not show
evidence of evaluating the final number, eg:
•    2.3 because I know it’s between 2 and 2.5
