Mathematics Challenge of the Week

24 May 2016

Part of learning mathematics is not just about the mechanics of algebra or how to use ideas such as Pythagoras’ Theorem or a cumulative frequency table, but just as important is for students to be able to select an appropriate method to solve a problem. 

  • Maths Challenge

This week’s challenge allows for just this type of opportunity and is called “Is there enough information?”

In triangle PQR, PQ = 7, PR = 9 and PM = 7.

Determine the length of QR.

You might look at this and say “I know how to do this problem.”

However, how many ways can you solve the problem to find the length QR and which way would be the most efficient for you?

If you have a solution and want to share – please feel free to send to me here.
