Students identify the appropriate type of graph for a statistical investigation about dice throws. They also justify the use of a histogram for an investigation about heights of people, indicating their understanding of discrete and continuous data.
Students construct a back-to-back stem-and-leaf graph for heights of trees. They then answer a question on range and make a statement comparing the heights of akeake and kōhūhū.
Students design school library badges by creating four symmetrical patterns using 2-dimensional shapes. A display board template is included for students to put their work on.
Students complete a table showing times to boil different quantities of water. They identify the rule that relates the amount of water to boiling time and use it to answer questions.
This practical task requires students to record data, which is read out to them, on a back-to-back stem-and-leaf graph. The leaves are then ordered into a second graph and the graph interpreted.
