Maths Resource Description
The game "Common Multiples" is an engaging mathematical activity designed to help players understand and find common multiples of single-digit numbers. To participate, players need a 0-9 dice and a blank number line ranging from 0 to 500. The aim is to take turns rolling the dice to generate three single-digit numbers, excluding 1 or 0. If a 1 or 0 is rolled, the player must roll again. With the numbers obtained, such as 4, 5, and 8, the player then calculates a common multiple of these three numbers and marks it on the number line. For instance, if the numbers rolled are 4, 5, and 8, possible common multiples to plot could be 40, 80, or 120, and so on.
The objective of the game is to be the first player to successfully plot four of their points on the number line without any of the opponent's points interrupting the sequence. To strategise and find common multiples, players might consider various methods. One approach is to multiply the three numbers together. Another is to list multiples of one number and look for common multiples with the others within that list. It's important to note patterns, such as if all the numbers are even, the common multiple will also be even. Additionally, if one of the numbers is a 5, the common multiple will end with either a 5 or 0 in the units column. This game not only sharpens multiplication skills but also encourages strategic thinking and pattern recognition.
