"Where the mind is without fear and the head is held high; Where knowledge is free; Where the world has not been broken up into fragments by narrow domestic walls; Where words come from the depth of truth; Where tireless striving stretches its arms toward perfection; Where the clear stream of reason has not lost its way into the dreary desert sand of dead habit; Into that heaven of freedom it should be our intent. ( my adaption from Rabindranath Tagores famous lines)

Sudoku_Beginners 4x4 with color symbols

Probably this would be more appealing than the digits 1 to 4 used in the last teaching exercise.

    great post. How long have you been blogging? I really love this blog and have added it to my favourites. I have just set up a website all about blank grid sudoku, perhaps you could take a look and let me know what you think.
