BAR GRAPHS REVIEW
Build, read, and question a graph

| Design | Coins held |
|---|---|
| Flat | 6 |
| Arch | 14 |
| Accordion | 22 |
| Tube | 18 |
- Build a bar graph. Include a title, labels, units and an even scale starting at zero.
- Could you use 1 coin per square on a grid with 16 rows?
- How many more coins did the accordion bridge hold than the flat bridge?
- Does this test prove the accordion bridge always works best?
Check your reasoning
A scale of 2 coins per square fits all values. A scale of 1 reaches only 16. The difference is 22 − 6 = 16 coins. One test cannot prove a design always works best; repeated trials would help.
Bar graphs compare categories. Their bars begin at zero, have equal widths and gaps, and use evenly spaced numerical intervals.
TAKE THIS TO YOUR TEST
Before you trust a graph…
01 / LookWhat are the categories? What is being counted or measured?
02 / CheckWhere is zero? What does one interval represent? Are units included?
03 / ThinkWhich numbers support the claim? What can’t this graph tell you?
