Primary Maths Challenge - 28 November 2014

The Primary Maths Challenge is an annual  event organised by  the Mathematical Association.  This year 20 children took part and gained either a Bronze, Silver or Gold award. It is basically a maths test but a lot of thought is put into the questions to make them appealing to upper KS2. There are 25 questions in total with the last five being very challenging indeed! Our results were:
Gold - 2 awards
Silver - 10 awards
Bronze - 8 awards
If anyone had scored 24 or 25 they would have been invited to the MA Headquarters in London to sit a further challenge.

Here's a sample of this years' questions;
