4 Digit Rounding

This educational game is designed to help students learn how to round four-digit numbers to the nearest ten. To participate in the game, each player will need a 0-9 dice and a blank number line that ranges from 0 to 10,000. The objective of the game is to practice rounding skills by generating four-digit numbers through dice rolls and then determining the closest ten that the number rounds to. For example, if a player rolls the number 4535, they must round it up to 4540, whereas if they roll 4534, it should be rounded down to 4530.

The game is played by taking turns to throw the dice, with each throw creating a unique four-digit number. Initially, players do not have a choice in assigning the thousands, hundreds, tens, or units place values; these are determined by the order in which the dice are thrown. After rounding their number to the nearest ten, players then mark their rounded number on the number line. The aim is to be the first to plot four points on the number line without any of the opponent's points interrupting the sequence. The game also provides an opportunity for discussion about the position of numbers in relation to multiples of ten. For instance, the number 2364 lies between 2360 and 2370. The rules for rounding are straightforward: if the units column is 5 or above, the number is rounded up to the next ten, and if it is 4 or below, the number is rounded down.
