Plotting Quadratic Graphs from Table of Values: Probing Questions
Whether you are looking for a question to stimulate discussion in lesson, or a challenge at the end of a homework, then hopefully you will find these useful.

I use Convince Me That questions lots in my lessons and homeworks. Providing students with a statement and challenging them to come up with as many different ways of convincing you as possible can lead to some fascinating discussions. The different ways of seeing the same thing can also help improve the depth of students’ understanding. Thanks so much to the Thornleigh Maths Department, in particular Erica Richards, Anton Lewis and Gareth Fairclough for helping me put these together, and we will endeavour to keep adding more!
Every single quadratic graph has a co-ordinate on them where x = -3
Not all quadratic graphs have a co-ordinate on them where y = 10
The graph of y=x2 has no co-ordinates with negative y values
Two x values may give the same y value
VI3 Treatment keyboard_arrow_up

We devised VI3 Treatment as a versatile way of giving students meaningful follow-up work at once we have marked their homework. The idea is that students are challenged to come up with 3 things with certain constraints. These are idea to use as an extension for students who have got everything correct, and also as further purposeful practise for students who have got a particular question wrong. Thanks so much to the Thornleigh Maths Department, in particular Erica Richards, Anton Lewis and Gareth Fairclough for helping me put these together, and we will endeavour to keep adding more!
Write down the equation of a quadratic curve
that has:
1) 0 co-ordinates where y = 4
2) 1 co-ordinate where y = 4
3) 2 co-ordinates where y = 4
Write down the equation of 3 graphs that cross the x-axis at (3,0)
Write down the equation of 3 graphs that cross the y-axis at (0, -12) and cross the x-axis at integer co-ordinates
