in year 5 we have played many maths games encluding a game called Addo. Addo is about finding the most affective board of numbers, as you can see at the top certain boards have a much higher chance of winning than others. some numbers are more common than others in certain spaces. The idea of the game is to find the best game board that wins 100% of the time. Numbers that are more in the middle have more combinations than others like to get 1 you could only draw a 0 and a 1 as for ten you can have sevrel combinations.
