Board games are not only used to teach counting, but also the speed of mathematical operations. You will see it!
Two players. To begin the game, take two game cubes. The two players throw the cubes at the same time. The task is to count the sum of the points and to write down it in the table as soon as possible. The winner is the player who correctly fills in the table for all 10 steps the quickest. A more complicated option is to calculate not the sum, but difference of points. An option for memory is to remember all the combinations of the points when the game is over.
