Growing Math Featured Lesson: Reading and Comparing Bar Graphs

Hello Educators! This is a Grade 6-7 math lesson, a part of the resources provided to educators in our Growing Math Project. It was previously featured on our site, but like with many of our resources, we’ve overhauled it for Growing Math!


CCSS.MATH.CONTENT.6.SP.B.5 Statistics & Probability: Summarize numerical data sets in relation to their context.

CCSS.MATH.CONTENT.7.RP.A.2.B Ratios & Proportional Relationships: Identify the constant of proportionality (unit rate) in  tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

Lesson Time

40- 50 minutes

Technology Required

Device with web-browser – Chromebook, laptop or desktop computer, iPhone or iPad


This activity is for Grades 6-7 and will introduce students to reading and comparing bar graphs with proportional relationships. Students complete a set of cards or complete activity in Google slides or Google doc.
Note: Business card stock may not be the best $10 I have spent as a teacher, but it’s high on the list. I  don’t know what it is about cards that makes something seem like a game but I have had the greatest success with activities like this one.

Preparing for the lesson – Options

Print out the cards if students do not have home Internet access or if you want to use the cards to do the activity in class.

If students are learning from home, you can copy the Google slides presentation to your Google classroom and assign to students.

1. Individual Activity

Print out the “Graphs” page or display it using a Smartboard, projector or in your Google classroom. Each student / group is required to complete the cards using the graphs provided.

2. Class Activity

After the students have completed the assignment, which should take around 10-15 minutes, have students share their findings to these questions with the class. Discuss and review the different questions and answers that can come from the same set of data.

3. Play Games!

Students can play the AzTech Games to practice statistics in this history adventure game series. Links are available from the games page.


AzTech Games Teacher Reports – Teachers can access standards-aligned student reports including answers to problems, number of correct answers, quiz results and pre-test/post-test results.

Students’ responses in the activities above, both individually and as a group, provide formative assessment of their ability at interpreting and extrapolating from graphical data.

State Standards

Minnesota Math Standard – Represent proportional relationships with tables, verbal descriptions, symbols, equations and graphs; translate from one representation to another. Determine the unit rate (constant of proportionality or slope) given any of these representations.
