I already answered this once tonight.

Draw a 3X3 grid. Number the rows 1 to 3, Number the columns 1 to 3. In each box of the grid, write in the number that is the sum of the row and column number. When you have filled in all nine boxes of the grid, see if you can find one of the boxes that contains a number that is not on the die.
