Looks good. I've given the question a more descriptive title.

Saved a checkpoint:

I've changed the randomisation so that:

• the weight is an unrounded number
• the cost of the bag always ends in 9p.
• The cost per 100g is between 50p and £2, which feels more reasonable. 

I've reworded the advice, and added a part asking to compare to a pick'n'mix price so that there's a reason for converting to price per 100g.

I've shortened the advice, as there were lots of statements repeated, for exampe giving the formula for the area, then justifying it with a diagram, and then giving the formula again. Fixed typos and reworded the questions to remove duplication of "the following..." in the statement and parts.

This is OK. Could have been more variation (other reflection lines, shapes overlapping the reflection line...), but not really worth an overhaul, as it fits in with the other transformation questions.

Originally split from a larger question on converting units, but basically a new question.

There was no mark assigned to part a). I've fixed that, but otherwise looks good.

Saved a checkpoint:

I've split the first two parts into separate questions.

Saved a checkpoint:

Split off from a bigger question but entirely rewritten. The original question asked to calculate someone's pay per hour as pay per minute, which I can't imagine ever wanting to do.

Chris Graham on Converting units of volume (cc/cm^3/litres/m^3) 8 years, 4 months ago

Gave some feedback: Needs to be tested

Chris Graham commented on Converting units of volume (cc/cm^3/litres/m^3) 8 years, 4 months ago

Split from a larger question, for which this part was incorrect. I've fixed the conversion for cm$^3$ to litres and removed the conversion to gallons, as this was not useful. I've replaced this with conversion from cm$^3$ to m$^3$, which is more useful, and a common problem for students.

I've ripped this apart enough to warrant marking it "needs to be tested" rather than "ready to use".
