## Project Euler- get students coding to solve maths problems

Could your students code a simple program to solve this maths problem? If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. ProjectEuler.net is a website that...

## AQA 90 problems to solve- perfect for 9-1 Maths GCSE

AQA have recently released their ’90 problems’ to support teachers in delivering the problem-solving element of the new 9-1 maths GCSE. It’s a rebranding of the 90 problems they released to support the teaching of Further Maths GCSE in 2008. There a number of issues with many of the diagrams on the newer version, so I’ve attached the 2008 version...

## Geometric squares

Look at the shapes in this square grid. The hexagons on each row, column and diagonal are made of the three shapes in that row, column or diagonal respectively. This completed ‘Geometric Square’ was posted on Twitter by @PardoeMary. Can your students create another geometric square? Can they create tessellation patterns of the results? What if you didn’t use hexagons, but...

## Metacognition… thoughts on teaching mathematical problem solving skills

How do you go about teaching problem solving skills? How do you teach pupils the thinking skills necessary to solve mathematical problems in contexts that are unfamiliar to them? These are difficult questions. I’ll declare upfront that I don’t have the answers to them fully. Nonetheless I have been researching and formulating possible approaches. This post shares with you where...

## Teaching the properties of equality through problem solving- repost from Keeping Mathematics Simple

I’ve found getting some pupils to understand the concept of equality to be surprisingly difficult. The problem seems to limit pupils’ ability in many other topics such as equivalent fractions, solving equations and changing the subject of a formula. I stumbled upon an article the other day that gave me some insight into why pupils struggle with it. When you...

## Making 100

Pupils write out the digits 1 to 10 like this: 1   2   3   4   5   6   7   8   9   10 The aim is to create an expression that equals 100 by putting as many + – X and / signs between the digits as they like. You might like to demo...
