M2.7.3 For the adult
Bar charts
The bar for Ball reaches the third line above 0. Is Ball 3?
What this chapter teaches
A bar chart has a scale that starts at 0 and goes up evenly. Read the number beside the top of the bar and do not count the lines. A taller bar means more.
Three questions to ask
There is no one right wording. Listen for the idea.
- How do you read how many a bar shows?
- What is the same and what is different between a bar chart and a pictogram?
- You have counts of 15, 10 and 20. What scale would you draw, and why?
After the chapter, the learner can
- Draw a bar chart with a scale going up in 5s
- Read a bar chart to compare groups
What they copy into their notebook
A scale starts at 0 and goes up evenly, here in 5s. Read the number beside the top of the bar. Do not count lines. A taller bar means more.
