Test A Mark Scheme
2002

1.	Award TWO marks for the 2 lines drawn as shown:	Up to 2m

	If the answer is incorrect, award ONE mark for at least one correct line drawn AND not more than one incorrect line drawn.
Do not award any marks if two or more incorrect lines are drawn.
[2]

2.	(a)	5 × 70 = 	1m
(b)	4 ×  = 200	1m
[2]

3.	Diagram completed as shown:	1m

Accept slight inaccuracies in drawing provided the intention is clear.
Accept answers without shading.
[1]

4.	(a)	80p OR £0.80	1m
Accept £0.80p OR 0.80 OR 80 OR £.80 OR £.80p OR £0 80 OR .80 OR 0 80
Do not accept £80p OR £80 OR £0.8 OR 0.80p
(b)	£2.25 OR 225p	1m
Accept £2.25p OR 2.25 OR 225 OR £2 25
Do not accept £225p OR £225
[2]

5.	Award TWO marks for the 3 shapes matched correctly as shown:	Up to 2m

	If the answer is incorrect, award ONE mark for any two shapes correctly matched.
Lines need not touch shapes or area boxes exactly provided the intention is clear.
Do not accept shapes on the left which have been matched to more than one area on the right.
[2]

6.	(a)	£2.45	1m
Accept £2.45p OR £2 45
Do not accept £245 OR £245p
(b)	CC	1m
Accept ‘C’.
Do not accept £1.55
[2]

7.	All three numbers circled as shown:	1m

Do not award the mark if additional incorrect numbers are circled.
Accept unambiguous alternatives, eg ticks, numbers crossed or underlined.
[1]

8.	Two cards ticked as shown:	1m

		OR

Accept alternative unambiguous indications such as circling or a line joining a correct pair of cards.
[1]

9.	 OR 	1m
[1]

10.	(a)	Answer in the range 44p to 46p inclusive.	1m
(b)	20p	1m
Accept £0.20p OR £0 20
Do not accept 0.20p OR £20p
[2]

11.	(a)	Award TWO marks for the correct answer of £21.80	Up to 2m
Accept £21.80p OR £21 80
	If the answer is incorrect, award ONE mark for evidence of appropriate working, eg
3.50 × 4 = 14.00
1.95 × 4 = 7.80
14.00 + 7.80 = wrong answer
Accept for ONE mark £2180p OR £2180 OR £21.8 as evidence of appropriate working.
Calculation must be performed for the award of ONE mark.
(b)	An explanation which recognises that each square slab costs more than half 
a rectangular slab or equivalent, eg	1m
•	‘Half of £3.50 is £1.75, which is less than £1.95’;
•	‘Two square slabs cost more than one rectangular slab’;
•	‘Because 12 squares cost £23.40’;
•	‘Because it would cost £1.60 more’.
Do not accept vague or arbitrary explanations, eg
•	‘Because he would need more slabs’;
•	‘Because square slabs are cheaper than rectangular slabs’;
•	‘Because it costs more’;
•	‘He is right because the square slabs are £1.95 each and the rectangular slabs are £3.50 each’.
[3]

12.	Digits written in boxes as shown: 	1m
44   +   38   =   851
[1]

13.	(a)	83mm OR 8cm 3mm	1m
Do not accept 8.3mm
(b)	29mm OR 2cm 9mm	1m
Do not accept 2.9mm
[2]

14.	8340	1m
[1]

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

	If the answer is incorrect, award ONE mark for two of the three numbers completed correctly.
For 0.25, accept .25 OR  
[2]

16.	0.21	1m
Accept .21
[1]

17.	(40, 27)	1m
Coordinates must be written in the correct order.
Accept unambiguous answers written on the diagram.
[1]

18.	(a)	Award TWO marks for correct answer as shown:	Up to 2m
	bags of
green apples	
	bags of
red apples	
Both numbers must be correct for the award of the marks.
	If the answer is incorrect, award ONE mark for evidence of appropriate working, eg
Listing of cost of apples:
75	90	
150	180	
225	270	
Calculation must be performed for the award of ONE mark.

(b)	An explanation that shows how it is possible to buy more apples but
spend less money, eg	1m
•	‘Nika buys 2 bags of red apples, giving 20 apples for £1.80, and Hassan buys 3 bags of green apples, giving 18 apples for £2.25’.
Do not accept vague or arbitrary explanations, eg
•	‘She got bigger bags than he did’;
•	‘She bought a lot of small ones’.
Ignore slight errors in arithmetic that do not contradict the explanation.
[3]

19.	5 and 6 written in the boxes in either order as shown:	1m

OR

[1]

20.	–60 in first box.	Up to 2m
Accept ‘minus 60’
Do not accept ‘60–’
–140 in second box
Accept ‘minus 140’
OR Do not accept ‘140–’
OR
	a number 80 less than the answer given in the first box provided both 	numbers are less than 0
If the answers given are ‘60–’and ‘140–’respectively, award ONE mark only.
[2]

21.	Award TWO marks for boxes ticked and crossed as shown:	Up to 2m

	If the answer is incorrect, award ONE mark for three out of four boxes correctly completed.
Accept alternative unambiguous indications such as Y and N.
Accept blank boxes as crosses.
[1]

22.	Award TWO marks for the correct answer of 42	Up to 2m
	If the answer is incorrect award ONE mark for evidence of appropriate working containing no more than one arithmetic error, eg
•	long division algorithm

Calculation must be performed for the award of ONE mark.
•	short division algorithm

Short division methods must be supported by evidence of appropriate carrying figures to indicate use of a division algorithm.
•	repeated addition / subtraction methods

No mark is awarded for repeated addition / subtraction the wrong number of times.
•	factor / multiple methods, eg

 [2]

23.	(a)	x = 	1m
(b)	y = 	1m
If the answers for (a) and (b) are transposed, but otherwise correct, award ONE mark only, in the (b) box.
[2]

24.	An appropriate explanation which recognises that:	1m

No mark is awarded for writing  alone.
OR

Do not accept vague or arbitrary explanations, eg
•	‘Because  is bigger than ’;
‘Because  comes first on a number line’.
OR
that is less than  because 3 × is greater than 1
