I'm not sure I want to include the same graph and part b, so I'm open to any suggestions of ways to introduce the 5 line equations.

You may find the code I used for this useful:

\[ \begin{align} x &=\displaystyle \frac{b}{a} \\&= \frac{\var{-k}}{\var{a}} \\&= \simplify{-({k}/{a})} \end{align}\]

This is a short and simple straightforward question so there is not much to change.

One thing you could do to improve the advice and explain the method a bit better - describe steps of calculating "we substitute $x=\displaystyle\simplify{-({k}/{a})}$ into.." so the student doesn't get confused where the final number -b/a comes from. Maybe even display it on its own line, so it would be something like:

"....we substitute

\[ \begin{align} x &=\displaystyle \frac{b}{a} \\&= \frac{\var{-k}}{\var{a}} \\&= \simplify{-({k}/{a})} \end{align}\]

into.....".

I have scrapped part e) as it didn't really fit with the question and it should now be fine.

Bradley Bush commented on Expansion of brackets 8 years, 6 months ago

Thankyou for the advice, I've added string restrictions, moved the answer boxes and i've added brackets to the advice. Although I haven't added fullstops on the end of questions because they're lone 1 line equations with no sentence sturctured around them 

Bradley Bush commented on Expansion of brackets 8 years, 6 months ago

Thank you for the feedback, I have fixed the string restrictions on all the parts, I've added the gap boxes and I've put more brackets into the advice but I haven't added the fullstops because the questions are one line and nowhere near a sentence, I'm not sure it's needed.

Lauren Richards commented on Algebra vocabulary 8 years, 6 months ago

• There is so much information in each part with all the options that it is a little overwhelming. It might be better to chisel down the options to include only the options that you think people may get confused with. Maybe 5/6 options for each part maximum. 
• ADVICE
• I think the first sentence in the advice needs to be reworded. It's a little clumsy at the moment.
• For part a), maybe explain that 3a + 2a is simplified to 5a because you've collected like-terms. 
• I feel like the "definitions" are too wordy. I actually feel like you should have a mathematical example either instead of or accompanying the word-definition. For example, for Factorisation, you have written "To put in brackets finding a common factor, this is usually the simplest form.". My thought process is that the user will be having to recognise and understand what the thing is when it is in a mathematical context rather than in a word-context. Therefore, I think you should write something like " for example 2x^2+x-3 = (2x+3)(x-1)".
• If you've included a quadratic, do you want to include a cubic as well?
