In the KS2 magic square to help teach the times tables there is a colour code. All multiples of 3  have green in the design ,for example squares 3, 6, 9 contain some green.

All the colours from 3 – 9 have their own colour code.

4 = YELLOW       5 = LIGHT BLUE     6 = RED           7 = ORANGE       8 = DARK BLUE     9 = PINK  PRIME NUMBERS = BLACK

         X           =    

So, the square 20 which is 4 x 5 would have yellow and light blue in the design:

        X             AND           X           =      

Some squares have more colours like 42 which is 6 x 7 and also 3 x 14 but only the numbers 3 – 9 are in the colour code so 42 contains RED, ORANGE AND GREEN (3,6 and 7)

PRIME NUMBERS:

The black squares are prime numbers the first prime numbers 1,2,3,5,7 and 9 don’t follow this rule as the times tables colour code takes preference.

Can you work out a pattern for the numbers on the white squares  ?
