Good intro to basic concepts. Part c) seems a little contrived though - there's no way I would let my daughter pick a pet at random! Also, the outcomes are probably not equally likely because the child probably doesn't like each type of pet equally, and within each group there are likely to be distinctions too. I would think of another example where it makes sense to be randomly assigned something or to randomly pick something. The numbers need to be variables and you should let the student know to simplify their answer.

I would remove the old bits. The same advice and more is now shown in the tables.

I think this looks good Elliott!

In parts b), c) and d) the expected answer isn't simplified. I got $1$ for part b) but the answer displays as $\displaystyle\frac{3}{3}$. I agree that it's important to include questions that involve flipping the inequality sign as you have in parts d) and g), but my concern is that you have entered the correct inequality for the student and they may not notice that it has been switched around as their answer would be the same either way. I know you've highlighted this in the advice but if the student gets their answer marked right, they'll not read the advice. It could be good to change a couple of the questions (one where the inequality remains the same, the other where it has changed) so they have the choose the correct inequality from a drop down as well as enter a numerical value.

In part g) of the advice, the wrong variable has been entered in the first line of the solution.

Thank you Vicky. I've added the tables now. I'm not sure whether I should keep the original advice for parts vii) and viii) or whether I should replace them completely. I've kept them there for now.

I really like the set up of this question and I think it will make the student think quite hard about properties of numbers. I've reworded some of the advice to make it clearer. I also think that, for consistency, parts vii) and viii) in the advice should have a table of values for $-3 \leq x\leq3$. It makes your conclusion look a bit stronger if you have checked a range of positive and negative numbers and can show a trend.

It isn't worth fixing the x*( issue so we have left it
