The game “Random Digits” demands Higher Order Thinking Skills (HOTS). The game starts with a common board for all players. The board is essentially for addition, subtraction or multiplication with two multi-digit whole numbers. It specifies the operations and the size, i.e., the number of digits of each whole number used in the operation. However, the exact digits are left blank. As the facilitator names each digit, players have to immediately place them on the board. Once placed, the position of a digit cannot be changed. Zero cannot be a leading digit, i.e., it cannot be placed in the leftmost box of any number. If a player is forced to do that, then s/he is disqualified. If the players choose to maximize the sum, difference or product, then the winner is the one with the maximum result (sum, difference or product). However, the players can choose to aim for the minimum as well. In both cases, players have to think where to place each digit in order to optimize his/her result. It is always a good idea to discuss the optimum result after each game. More details on the game can be found at https://shorturl.at/hkxV3
