Concrete and Pictorial Graphs

A graph is a tool for answering a question. This is the most important thing students should learn about data in Kindergarten. Before making a graph, there must be a real question: 'How did you get to school today?' 'What is your favourite fruit?' 'Which colour of linking cube do we have the most of?' The graph exists to answer that question — and mathematical discussion of what it shows is as important as making it.
