First we learned how to create picture graphs using Google Draw.
Next, students learned how to create a simple survey using Google Forms.
The class took their classmates' surveys and then looked at their own survey's data that was collected in a Google spreadsheet.
Here is my survey... and the class learned how to use conditional formatting so that they could visually see the response differences for counting.
Even though Google Forms shows a Summary of Responses (why not learn another cool trick?).
After the class found out how many people chose each choice, they made a bar graph with the insert chart function of Google spreadsheets.
Here is a graph from the survey form shown at the top of this post. It was embedded into a Google Doc so it can be easily put on a Google Site page.
