Max Maths, Year 6, Learn together, Mode, range, median and mean (3)

In Max Maths for Year 6, students are learning to calculate the mean of a set of numbers, which is a fundamental concept in understanding averages. The mean, often referred to as the average, is determined by adding together all the numbers in a set and then dividing this total by the number of items in the set. For example, to find the mean number of buttons in three groups, students first count the buttons in each group, which are 5, 7, and 12 respectively. Adding these together gives a total of 24 buttons. Since there are 3 groups, dividing the total number of buttons by 3 results in a mean of 8 buttons per group.

Similarly, when finding the mean number of squares across four groups with quantities of 16, 18, 10, and 28, students add these numbers to get a total of 72 squares. To calculate the mean, this total is then divided by the number of groups, which is 4 in this case. Performing the division gives a result of 18, so the mean number of squares per group is 18. These exercises help students understand how to work with data sets and calculate averages, which is a crucial skill in mathematics and data analysis.
