my son has been given this from his maths teacher.apparently even she can't do it.

got a grid of squares 4x4.

got 8 title cards which must go along the top or side. they are as follows :- prime number, square number, odd number,even number,triangular number, multiple of 5,multiple of 3,multiple of 7.

the numbers to fit in the grid are:-

1,2,3,5,6,7,9,10,11,15,16,21,28,30,35,49.

we have got so far and been left with 1 number that doesn't fit!!!!

Spent hours on this and it's driving us mad.
