Overarching  learning  goals: This lesson provides students with opportunities to engage with real world data yielded by the Garage Sale they hosted. Students will analyse graphic organisers that present data collected from last year’s Garage Sale Trail event. They will use these models to create their own graphs, charts and tables. They will also discuss the results of their Garage Sales in terms of sales figures per category of item.   

Work through this resource material in the sequence suggested here.

NOTE:  To complete these tasks, you will need to have compiled the following data sets from the Garage Sale events in which your students were involved:

  • stock lists from each Garage Sale hosted by students from the class
  • stock categories for each stock list
  • rough profit figures for each sale
