Playing the magic square puzzle...

...with my 10 year old Vietnamese student as an exercise in numeric thinking and logic. These puzzles are not so easy unless you have a little insight.

Give it a go! It is only level4. For a 4*4 square the numbers are 1-16 so each row, column and diagonal adds to 16*17/8 =34
This is an even numbered magic square so it gives some additional properties about the 4 corners and the centre quadrant which make this one much easier.
He does pretty well at these, but I think we should jump to level 6.
As a hint to start with, we know the sum of R1C1+R4C1 so we immediately know the number in R2C1.
