This is a harder version of the 2x table calculator game, published earlier in that the grid has larger multiples of 2. All you need is the grid, some counters or cubes and a calculator. Set the calculator up as a 2x table answer machine by keying in 2, x, x, =, 0 and then all you need to do is press a number and the equals sign and it will show the answer to the number multiplied by 2. Just type in the next number, press equals and so on…
Once again, the aim of the game is to make a line of four in a row in any direction.
