"It's a hairy situation," I said with a laugh.
"But we can keep track with a simple bar graph."
I wrote numbers on the left from 0 [zero] to 15.
Across the bottom I wrote hair colors — no, not green!
Above each choice I colored one square
For each student who has that color of hair.
Our teacher, Ms. Muller, was really impressed.
For comparing amounts, she says graphs are the best!
