Mark scheme (a)

Gives a list of at least 3 year groups, e.g. '7, 8, 9, (10, 11, 12, 13)', ‘reception, 1, 2, (3, 4)', OR states, e.g. ‘Year Group boxes’, ‘Year 7 – Year 11’, ‘Year 7, Year 8 and so on’ ‘Year 7 to 9, Years 10 and 11’
B1
In either order Allow if at least 2 groups are given, with no overlaps or repeats, e.g. ‘Key Stage 3, Key Stage 4’
Gives options, e.g. 'yes, no, (don’t care)' , 'yes, no', 'yes, no, other' OR states, e.g. ‘yes and no boxes’
B1
Corrected by Westie's Workshop
The board's mark scheme printed “Allow if a least 2 groups”. Changed to “Allow if at least 2 groups” because “a least” is a misprint for “at least”.

(i) Black
B1
(ii) Measures the angle 60° ± 2°
B1
Check diagram FT for 60° ± 2° Allow for appropriate sight of 60, e.g. 60/100, 60%, 60 people, but not as a denominator. Example of inappropriate sight of 60: 300/5 = 60 or 300 ÷ 5 = 60, B0
(Fraction) 60/360
M1
FT 60° ± 2° but ≠ 60° for M1 only Allow sight of 300 × 60/360 or 6/36
1/6
A1
CAO Allow B1, M1, A0 for an answer of 50 (people) Award B1, M1, A1 for an answer of 1/6 from sight of 360/60
Alternative: 50/300 M2 1/6 A1
If no marks, award SC1 for FT ‘blue’ from (b)(i) for an answer of (75/300 =) ¼ in (b)(ii)
Corrected by Westie's Workshop
The board's mark scheme printed “FT ‘blue’ from (a) for an answer of (75/300 =) ¼ in (b)”. Changed to “from (b)(i) … in (b)(ii)” because the colour is chosen in part (b)(i) and the fraction is worked out in part (b)(ii); part (a) is about option boxes.
