My DSD (12) had the following questions: (I'm paraphrasing btw as I don't have it with me)
- Teacher needs the following equipment for her lesson: 1 book per pupil plus 1 spare. 3 worksheets per pupil. 2 rulers per pupil plus 7 spare.

w=
___
(b) work out how many of each item is needed if there are 12 pupils.
- (picture of triangle) an equilateral triangle has perimeter p. We work out the length of one side by using s=p/3.
(a) If the perimeter is 6cm how long is one side?
(b) rearrange the formula to make p the subject: p=
___
- (picture of regular hexagon) this hexagon has side length s.
(a) Write a formula for finding the perimeter p=
___
(b) if one side is 6cms how long is the perimeter?

DSD really struggled with it. She generally does ok at maths but I think algebra confuses her (she's dyslexic too). I would have thought that an average student could do that in yr7 but I'm willing to be corrected - I was in a very pushy selective school and thanks to my dad's genes found maths easy.
I'm really worried about DSD struggling :( she's finally found her niche at secondary after hating junior school - she's quite a sciency person and enjoys it but if she falls behind in maths again it'll really knock her confidence - last term she was top of the class working at level 8 on indices stuff which was a doddle for her.
Any advice/thoughts please?
