[1]

5.	(a)	32	1
(b)	5	1

appropriate method, eg
	840 ÷ 20 OR 8.4 ÷ 0.2
Accept for ONE mark, £42 OR 42p as evidence of an appropriate method.
Answer need not be obtained for the award of the mark.
No method mark is awarded for 8.40 ¸  20 alone.

appropriate method, eg
	2.25 × 60

Accept for ONE mark £135p as evidence of appropriate method.
Calculation need not be performed for the award of the mark.
[3]

11.	Any rectangle with an area of 14 squares, eg	1

Rectangle need not be shaded or coincident with the grid lines. Accept extensions to the grid to allow, for example, a 14 × 1 rectangle.
Accept slight inaccuracies in drawing provided the intention is clear.
[1]

12.	Explanation which recognises that the largest two-digit number (99) added	1
to itself only gives a three-digit number (198), eg
•	‘Because if you do 99 + 99 you only get a three-digit number’;
•	‘If you add any 2 two-digit numbers, you will get a three-digit number or a
two-digit number’.
No mark is awarded for circling the ‘Yes’ alone.
Do not accept vague or arbitrary explanations such as
•	‘The numbers aren’t big enough’;
‘It doesn’t work’.
If ‘No’ is circled but a correct unambiguous explanation is 
given then award the mark.

Accept the answer in words, eg 
•	‘1000 and a half’.
[1]

15.	Award TWO marks for the correct drawing as shown below: 	Up to 2m

Shape need not be shaded.
Accept slight inaccuracies in drawing, provided the intention is clear.
	If the drawing is incorrect, then award ONE mark for the shape correctly orientated
but rotated about the wrong point (or a relocated ‘A’), eg

	OR shape rotated 90° about A, but anti-clockwise, ie

	OR a stretching or contraction, by one square, of the length of the shape, which has otherwise been correctly rotated, eg

[2]

(b)	8	1
[2]

19.	(a)	40	1
	(b)	Answer in the range 12 to 13km inclusive.	1
(c)	An explanation which indicates that after 1 hour she has travelled more	1
than 20km and/or she has travelled less than 20km in the second hour, eg
•	‘She did about 40 km and it was about 22 in the first hour’;
•	‘Half and half would be 20-20, but she does more than 20 then less than 20’;
•	‘It goes to 23 in the first hour’.
Do not accept vague or arbitrary explanations, eg
•	‘She got tired in the second half’;
‘It’s marked on the graph’;

22.	An explanation which recognises that the angle at the pivot for the region 
containing 1 is 180° or half a turn on both spinners, eg	1
•	‘It’s half the turn of the spinner on each’,
•	‘They are both 180°’;
•	‘On both spinners the probability of scoring 1 is ½’.
Do not accept vague or arbitrary explanation, eg
•	‘It’s one out of three on each’;
‘1 is the same space on both’;
‘They are both equally good at spinning’;
