Lauren Richards on Finding the highest common factor of two numbers 2 years, 4 months ago

In part c)i), ii) and iii), I really wanted the individual factors to be listed for each number, and then for the common factors in each individual list to be highlighted but I didn't know how to do this and I think Chris mentioned something would have to be created in order to do this.

  • I've made sure that the solutions are integers but that has meant that the question is not randomised. 
  • I'm also having a little trouble in centering a section of part a) which includes an overline and a subtraction.
  • Otherwise, I've made all the changes you requested. 

Lauren Richards on Calculating Expected Values given a table of probabilities 2 years, 4 months ago

  • I think the question statement should just be right at the start of the advice. 
  • I actually think the two parts should be completely separate questions. There are definitely enough individual questions in part b) to make it a good lengthy question with i), ii) and iii) as individual parts that can be marked separately. You can relatively easily add in another question part for part a) to lengthen it if you wanted to. Maybe something about age ratings or something. 
  • b)ii) I would programme in a fraction with gap fills so they can answer it like that rather than getting them to do a fraction with no fraction sign and no instruction to do it like a/b. 
  • I think this is a great question, and I can't find very much wrong with it at all, well done Elliott! 

Lauren Richards on Calculate the original price before a decrease 2 years, 4 months ago

  • Are you absolutely sure you want to pick fridge as an option for the object? The scenario talks about Josh really liking Emily's fridge and thus buying it on a bit of a whim, but I don't think that really happens with fridges! I think you'd only purchase it if your fridge happened to be broken. It is quite funny though so up to you whether you keep or change it. 
  • I would reword parts of the question slightly, just to make the focus a bit stronger. Part a) - "When Josh told Emily how much he had paid for the {item}, Emily said the price had decreased by 30% since she bought it. How much did Emily pay for the fridge?"
  • Good, clear advice!
  • I think the question is really good and a valid real-world example scenario!

I have made the changes you suggested and made sure the LCM will not be either of the given numbers.
