Human Bar Graph!


Tip: Make a human bar graph!

How do I do it?
Ask an opinion question related to what you are studying and students line up under strongly disagree, disagree, neutral, agree, strongly agree signs that are posted along one wall of the classroom.  For example, "George Washington was the best president" or "The post office is the best place to meet people in a city" or "The legal age to drive should be raised from 16 to 20" or "Plants are better than animals." etc.  Post the opinion and direct students to line up under the sign that best matches their answer. Then, create a graph for each opinion.  By using stick figures, it will help students understand the results.

Variations & Extensions:
Once students are lined up ask them to work together to agree on the 3 top reasons they hold that opinion/are in that line and lines share their reasons one by one.  After all lines have shared their reason for being there, people may change lines if they are convinced.  You can require the line changers to state why they are moving or allow them to move without reasons.  Students can write a summary of the class opinions as a whole class, in small groups, pairs, or individually.  The beginning and/or ending bar graph can be recorded and posted.  The same question can be asked over a unit of study to track changing opinions over time.
