M2.7.6 For the adult
Line graphs
I measured my plant every day. How do I show it growing?
What this chapter teaches
A line graph shows change over time. Put a point for each measurement and join them in order. The points are measurements and the line between them is an estimate. Fruits or games are choices, so they do not belong on a line graph.
Three questions to ask
There is no one right wording. Listen for the idea.
- Which things would you show with a line graph, and which with a bar chart?
- How would you find the height halfway between day 4 and day 5, and how sure is it?
- How can you tell from the line when the plant grew fastest?
After the chapter, the learner can
- Read values from a line graph that shows change over time
- Draw a line graph of a seedling's height each day
What they copy into their notebook
A line graph shows change over time. Put a point for each day and join them in order. A point is a measurement. The line between points is an estimate. Do not join fruits or games.
