Activity
This game gives the students practice in recognising the factors of numbers.
To help the students play strategically, you could ask questions such as: “Which is the best position to choose?” You may want to discuss whether the students are allowed to block the path of the other player. (It is not forbidden in the rules and is part of the strategy in many games.)
As a variation, some students might enjoy the challenge of changing the numbers on the dice and then changing the numbers on the game board to multiples of the numbers that are now on the dice.
