Background For Teachers:
Displaying data clearly can help you prove a point. It can also help you to discover patterns/trends in your data. Clear displays can help you see trends, make predictions, and compare ideas. Graphs help you to see the “big picture” hidden in your data.
A big part of showing data clearly is choosing which kind of graph to use. You might use a Venn Diagram to show how the students’ family pet data are related to each other. You might choose a line graph to show how a baby tiger gains weight as it grows. To compare the number of games your favorite team has won, you might select a bar graph. Only introduce one graph per day.
The most effective way to introduce young children to the concept of gathering data and transferring that data onto a graph is to start with a pictograph, and then gradually explore the many and varied kinds of graphs as new and different data are gathered. Keeping a math journal as you go is also very important to help children see their progress and review concepts.
Intended Learning Outcomes:
Invitation to Learn
Guiding questions: What are the different kinds of graphs that were used to show the tiger’s growth? How do graphs show “the big picture?”
