Common Multiples 1

This engaging mathematical game is designed to help players learn how to find common multiples. Participants will need a dice numbered from 0 to 9 for the activity. The game is played by taking turns to roll the dice, which will determine two single-digit numbers. Once the numbers are rolled, players must work out and declare a common multiple of the two numbers. Points are scored based on the common multiple declared: if the multiple is the exact product of the two numbers, the player scores 1 point. However, if a player is able to declare a lower common multiple that is not the direct product, they score 2 points. For example, if a player rolls a 6 and a 9, declaring 54 (which is 6 multiplied by 9) would score 1 point, but declaring 18, a lower common multiple, would score 2 points.

The objective of the game is to be the first player to accumulate 10 points. The game also incorporates a discussion element, encouraging players to talk about the position of numbers in relation to whole numbers. For instance, they might consider that 3.4 lies between the whole numbers 3 and 4. Additionally, the game includes a rounding component, teaching players that when rounding numbers with a tenths column value of 5 or higher, they should round up to the next whole number, while a tenths column value of 4 or lower should be rounded down. So, in the case of 3.5, it would round up to 4, whereas 3.4 would round down to 3. This game not only aids in understanding multiples but also reinforces number placement and rounding skills.
