1.	(a)	65	1m
(b)	8	1m
(c)	180	1m
[3]

2.	£0.65	72p	£2.88	£5.40	£10	1m
Accept answers with missing or incorrect units.
Accept a misread of the amounts provided this does not alter the correct order intended by the question.
Accept the reverse order of the amounts.
[1]

3.	(a)	12p	1m
Accept 12 if written outside the answer box.
(b)	85p OR £0.85	1m
Accept 85 OR 0.85 OR .85 OR £0.85p
OR £.85 OR £.85p OR £0 85
Do not accept £85p OR 0.85p OR £85
[2]

4.	Diagram completed as shown:	1m

Shape need not be shaded.
Accept slight inaccuracies in drawing provided the intention is clear.
[2]

5.	1060	1049	1100		899	1m
Accept alternative indications, eg the number crossed or underlined.
[1]

6.	Completion of rectangle as shown:	1m

Accept slight inaccuracies in drawing provided the intention is clear.
[1]

7.	90p OR £0.90	1m
Accept 90 OR 0.90 OR £.90 OR £.90p OR .90 OR £0.90p OR £0 90 
Do not accept £0.9 OR £90p OR 0.90p OR £90
[1]

8.	Award TWO marks for the table correctly completed as shown:	Up to 2m

	If the table is not correctly completed award ONE mark for any two out of three ticks correct.
Do not accept any row that has both columns ticked.
Accept unambiguous alternatives to ticks, eg ‘yes’.
[2]

9.	
	
	(a)	3 in left hand box	1m
(b)	2 in right hand box	1m
[2]

10.	(a)	09:55 OR 9:55	1m
Accept 21:55 OR 955 OR 2155 
Accept ‘five to ten’ or equivalent.
Ignore am or pm. 
(b)	11:45	1m
Accept 23:45 OR 1145 OR 2345 
Accept ‘quarter to twelve’ or equivalent.
Ignore am or pm.
[2]

11.	121	1m
[1]

12.	Award TWO marks for numbers placed in boxes as shown below:	Up to 2m

	If the answer is incorrect, award ONE mark for two numbers correctly placed.
Do not accept a number repeated in different boxes.
Ignore any numbers on the diagram other than those given.
[2]

13.	270°	1m
[1]

14.	Award TWO marks for the correct answer of £2.47	Up to 2m
	If the answer is incorrect, award ONE mark for evidence of appropriate working, 
eg (4 + 6 + 7) –14.50 = 2.50
250 – 3 = wrong answer
Accept for TWO marks £2.47p OR £2 47 
Accept for ONE mark £247p OR £247 OR 2470 OR 24.7 as evidence of appropriate working.
Calculation must be performed for the award of ONE mark.
[2]

15.	(a)	Statements ticked and crossed as shown below:	1m

Accept alternative unambiguous indications, eg ‘Y’ or ‘N’ 
Do not accept statements, which are not ticked, crossed or otherwise clearly marked.
(b)	An explanation which recognises that	1m
the highest possible score on each spinner
is 3 and that 3 + 3 < 7, eg 
•	‘The best score is 3 + 3’;
•	‘On the spinners there are only the numbers 1 to 3 so they must add up to less than 7’;
•	‘Because even if you add the highest number on each spinner the answer would be 6’.

No mark is awarded for circling ‘Yes’ alone.
Do not accept vague or ambiguous explanations, eg 
•	‘Because 1 + 2 + 3 do not add up to 7’; 
•	‘The numbers add up to less than 7’; 
•	‘I know because they won’t add up to more than 7’.
If ‘No’ is circled but a correct unambiguous explanation is given then award the mark.
[2]

16.	689	1m
[1]

17.	(a)	Answer in the range 101mm to103mm inclusive.	1m
(b)	Answer in the range 21 degrees to 23 degrees inclusive.	1m
[2]

18.	Award TWO marks for the correct answer of 12216	Up to 2m
	If the answer is incorrect, award ONE mark for evidence of appropriate working which contains no more than ONE arithmetical error, eg 
•	conventional algorithms such as:

In all cases accept follow through of ONE error in working.
Do not award any marks if: 
•	the error is in the place value, for example the omission of the zero when multiplying by the 2 tens; 
•	the final (answer) line of digits is missing.
Variations on algorithms are acceptable, provided they represent viable and complete methods.
OR
•	decomposition methods, eg
24 × 500   = 12000
24 × 9      = 216
12000 + 216  = wrong answer
Calculation must be performed for the award of ONE mark.
[2]

19.	Fractions completed as shown below:	1m

All three fractions must be correct for the award of the mark.
[1]

20.	(a)	(15, 40)	1m
(b)	(20, 0)	1m
Accept answers written on the diagram with or without brackets and commas.
Coordinates must be written in the correct order.
