This class has completed Chap 1. To stretch them further, they were tasked to try Qns 14 & 16 of Review Questions 1 from their textbooks. These 2 questions require them to prove before solving the cubic equations.
I got a pupil to come up to present the proving part of the 1st question. She tried but was not confident of doing it so I allowed her to get one of her classmates to come forward to help. As the 2 were doing on the whiteboard, I went round the class to see what the rest had done. Some did not do anything as they were not sure how to start as they told (but I suspect they did not prepare at all). As I went round, I spotted some common errors.
Some pupils wrote -2^2 when the correct way of writing is (-2)^2. Quite a no of them thought that -2^2 is the same as (-2)^2 with both answers as 4. Hence, we had a discussion on the difference between the two. It was a good discussion as I helped them to clear their misconceptions.

I think my 2E1 has the same problem as your class as well but luckily the misconceptions were cleared as well.
