Going in ascending order, 5, 4 and 1 make a number bond to 10.Ĩ and 4 make 12, so this gives a total of 32. This means that students will need to first find the total number of books read by the class.Īs they are in 6th grade, I would encourage them to use their mental arithmetic skills to find the total by looking to make number bonds that they are comfortable with. NameĪs mentioned earlier, to find the mean average value, you must first add up all the data points and divide the sum by the total number of values. Here’s a frequency table containing discrete data (rather than grouped data) with no outliers. This can be obtained in different ways, but it is more meaningful when it can be related to your class. To find the mean, you first need a set of values. With all data the same height, we can see that the mean average is the size of each part when a quantity is shared equally. This is demonstrated in the next picture. We can see that by removing two orange cubes and placing them on top of the blue cubes, then all data points would have the same value. Read more: Concrete Representational Abstract The way to do this would be to see if we can get all data points to the same height by manipulating the data (when doing this with a class, I would get them to make these representations physically with cubes or counters). While this reaches the answer of a single number, it does not provide a conceptual understanding of what is happening to that data.īefore getting students to carry out an algorithm, it would be better to demonstrate to them what is happening when they carry out this process.īy finding the mean, we want to find the average points scored in a game across all teams. If this represented a data set of points scored by four teams in a game, we could find the mean by adding up all the data points and dividing the sum by the number of data points in total. However, it is important that students understand what is happening when they are finding the mean of a data set. Mean is often taught and explained through abstract methods as soon as students in 6th grade are capable of manipulating the required numbers needed to find the mean or average amount.
