Students learn about drawing stem and leaf diagrams using a key. More able students are challenged to plot back to back diagrams. Less able students are given the key and work mostly with tens and units.At the start of the lesson students recap finding the median, mean and range from a set of data. In the main part they learn how to plot and read stem and leaf diagrams using a key. In the plenary they are challenged to draw a stem and leaf diagram from primary data.
