1. Changing the Intervals and Scale on a graph
Grade 6 Data Management Unit

2. Re-cap What is the purpose of a double bar graph?
What are ways we could separate data in this class?

3. Intervals
Intervals are the distance between two points on a graph, chart, plot, or grid
Where are the intervals on this graph?

4. Think, Pair, Share
Re-create this bar graph in your groups by increasing the intervals.
What do you notice happens to the appearance of the graph when you increase the intervals?
What do you think would happen if you decrease the intervals?

5. scale
The horizontal scale across the bottom and the vertical scale along the side of a graph tell us how much or how many.
What is the scale on this graph?

6. Think, Pair, Share
In your Math groups, look at the scale. If you were to change the scale from kilometres to metres, what would happen to the appearance of the graph?

7. Task Refer to the double bar graph you created for homework.
Re-create your graph by increasing the intervals on the graph through this website:

What has happened to the appearance of your graph in comparison to the original
