Notice and Wonder: Bar Graph Scales (Warm Up)


1.

What do you notice?

2.

What do you wonder?

Represent Pattern Blocks

Here is a collection of pattern blocks.

Mai, Noah, and Priya want to make a bar graph to represent the number of triangles, squares, trapezoids, and hexagons in the collection.
  • Mai says the scale of the bar graph should be 2.
  • Noah says the scale of the bar graph should be 5.
  • Priya says the scale of the bar graph should be 10.
3.

Who do you agree with? Explain your reasoning.

4.

Use the scale that you chose to create a scaled bar graph to represent the collection of pattern blocks.

Represent More Data in a Scaled Bar Graph

All the third-grade students at school were asked, “What is your favorite time of the year?” Their responses are shown in this table:
