Week 5 - A square of numbers

Picture 1

This week's problem involved using all 4 operations. We had to use all of the numbers from 1 to 8, but could only use each number once. When we put each number into the circles, all of the number sentences had to be correct. 

 

So as we began to tackle the problem, it soon became clear that it wasn't going to be as easy as it had first looked! Most people tried starting in one box and working their way around the square answering the questions. This was good until a number was repeated or wasn't available, which was very annoying. 

 

As time passed and the children were developing strategies, with varying levels of success and frustration, they were all determined to find the outcome which some people did! Have a look at their result and explanation of how they did it below.
