Rounding is a math strategy that uses addition & division strategies. Rounding means making a number easier but keeping its value close to what it was. The answer is less detailed, but easier to use
Addition and division are both operations that are used for rounding. To round, the person needs to find the mean, to find the mean get a set of numbers like 5,7,1,9,3 and then add them altogether which would make 25. Then divide them by the amount of numbers there are which makes 5.
Rounding can help people get better at adding and dividing. Also at understanding how to round numbers in to 1 decimal place.
