Powers and roots

This  collection of resources supports the teaching of powers and roots in secondary mathematics.


Here are some favourite activities selected by the NRICH team.


  • Sticky Numbers Can you arrange the numbers 1 to 17 in a row so that each adjacent pair adds up to a square number?
  • Generating Triples Sets of integers like 3, 4, 5 are called Pythagorean Triples, because they could be the lengths of the sides of a right-angled triangle. Can you find any more?
  • Power Countdown In this twist on the well-known Countdown numbers game, use your knowledge of Powers and Roots to make a target.

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


The activities below, taken from the STEM Learning website, complement the NRICH activities above.
