Teaching AO2

AO2 – Select and apply mathematical methods in a range of contexts

What this means: Problem-solving – find the ordinary maths you need to get you to the correct answer. The question will often give you a hint. Worth approx 25-35% of marks in the exam.

…So it’s worth making sure you know how to do AO2 and AO3 questions!

Note: The exact proportion of marks available in the exam varies with each Assessment.

AO2 Example, from 5.4 Lines of Best Fit

Note: In Q3d, students must use lines of best fit to make estimated marks. Emphasise that they may need to make predictions without being told to draw a line of best fit, so they must make that decision.
