How to convert worded problems to solvable inequalities.

Note that in September I am due to start as a trainee maths teacher . For my interview, I taught a lesson on inequalities to a class of GCSE pupils. In particular, we focused on converting worded problems to solvable inequalities. I would start by displaying a problem, and working though it with the student (I would first send them a pdf of a list of questions that we will work through so it is infront of them). Structure outline:Question 1: go through together with the pupilQuestion 2: this will be very similar to Q1, so the pupil is able to talk through it alone, using the method used in Q1.Question 3: something a bit more challenging, perhaps they might need a hint etc.
