## Summary

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.

## Lesson Plan

### 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.

## Assessment

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.
