NOW, FIFTH CLASS, put your books away and fold your arms. You. Yes, you. In the back. Pay attention.

Now, a pháistí, I hope you all had a lovely summer – but you’re back to school now and we need to see just how much you remember from maths last year.

Now – you! I said pay attention! – this is a test just like the one you did at the end of 4th Class. I’m going to give one out to each of you, and depending on how you do, we’ll see if there’s some bits from last year that we need to go over again.

Extra question for bonus marks:
Let’s pretend you’re running a boxing competition in which 15 people are taking part. Each fight will have four rounds each, where each round has three minutes. Assuming that no fights are stopped early, how many minutes of fighting will take place before a winner has been found?
(As soon as a boxer loses, they’re out of the competition. You can ignore the breaks between rounds, and should try to make sure that every entrant has to fight as many times as possible in order to win. )
