In numeracy this week we have been trying to find patterns in magic squares. Magic squares are normally a 3 by 3 grid where you need to put numbers in to make fifteen. Every column, row, and diagonal needs to add up to fifteen. We were doing it with 3 sets of 3 numbers. We had 6 challenges to do with magic squares. Underneath are two of them.
As you can see there are fives going diagonally down the middle. This determines that the magic number is fifteen. Each number needs to have the same difference from the middle number which in this case is 5. 3 is 5-2 and 7 is 5+2. We are currently working on harder magic squares which includes algebra.
