1

Hook — A Picture of the Numbers

5 min

A bar graph shows each amount as a bar, so taller means more. That makes it quick to see which is biggest. But how do you read the exact number a bar stands for?

👩‍🏫 Teacher Moves

  • Show a simple bar graph.
  • Ask which bar is tallest.
  • Set the goal.

🎒 Student Actions

  • Think.
  • Share.
  • Get ready.
2

Use — Graph Check

12 min

Students answer questions about a bar graph.

👩‍🏫 Teacher Moves

  • Send students to the Graph Check.
  • Answer each question.
  • Read the why.

🎒 Student Actions

  • Answer.
  • Check.
  • Read it.
3

Modify — Read the Scale

13 min

Students use the scale to read bars.

👩‍🏫 Teacher Moves

  • Pick a bar.
  • Use the scale to find its value.
  • Compare it to another bar.

🎒 Student Actions

  • Pick.
  • Read.
  • Compare.
4

Create — My Own Bar Graph

15 min

Students build a bar graph.

👩‍🏫 Teacher Moves

  • Collect a small set of data.
  • Draw bars with a clear scale.
  • Write one question about it.

🎒 Student Actions

  • Collect.
  • Draw.
  • Write.
5

Reflect — Comparing with Bars

5 min

Students reflect on bar graphs.

👩‍🏫 Teacher Moves

  • What does the scale on a bar graph tell you?
  • How do you find how many more one bar is than another?
  • Complete the exit ticket.

🎒 Student Actions

  • Say it.
  • Say it.
  • Complete the exit ticket.

QUESTION 1
What does the scale on a bar graph tell you?
The value of each line or step on the axis, so you can read the exact number each bar reaches.
QUESTION 2
How do you find how many more one bar is than another?
Read both bars' values and subtract the smaller from the larger.
QUESTION 3
On a bar graph, what does a taller bar mean?
A greater amount: bar height stands for the number.

Create: my own bar graph.

Have students collect a small set of data, draw bars with a clear scale, and write one question about it, so reading a graph connects to making one. A printable bar-graph worksheet is in the Mathematics library.
