Functions & Graphs - Stage 4

This collection of resources that support the teaching of Equations and Formulae.


Here are some of the favourite activities selected by the NRICH team.


  • Perpendicular Lines Position the lines so that they are perpendicular to each other. What can you say about the equations of perpendicular lines?
  • What’s that Graph? Can you work out which processes are represented by the graphs?
  • Parabolic Patterns The illustration shows the graphs of twelve functions. Three of them have equations y=x^2, x=y^2 and x=-y^2+2. Find the equations of all the other graphs.
  • Surprising Transformations I took the graph y=4x+7 and performed four transformations. Can you find the order in which I could have carried out the transformations?

These are just a few of the activities on Functions and Graphs that you can find on the NRICH curriculum pages.
