                    Using the numbers 1 – 9, fill in the boxes below to
                    make a “magic square”. Each number can be used only
                    once and there must be the same sum horizontally,
  by Frank Murphy   vertically and diagonally.

Extra squares if you need them.

Does this pattern work for other sets of consecutive numbers? Experiment with the
following and then choose your own numbers for parts e and f:
a) 5,6,7,8,9,10,11,12,13       b) 2,4,6,8,10,12,14,16,18     c) 1,3,5,7,9,11,13,15,17

d) 5,10,15,20,25,30,35,40,     e)                             f)
