Multi-Bar Graph 7.11A

I use Statcounter to track visits to my blogs. Below is tracking from my TAKS Math Blog. It is displayed as a multi-bar graph. Each color represents how the data has been collected. It tells me how often people visit my blog, who returns, and how many page loads occur.

Daily | Weekly | Monthly | Quarterly | Yearly

Constructing Pie/Circle Graphs 7.11A

Yesterday my classes all took a survey of their favorite classes. Each student chose only one subject as their favorite. The end result was the class as a whole constructing their own pie chart, breaking down the totals, turning them into fractions, decimals, percents, and finally degrees, so the pie could be cut into parts according to the angles. Quite a few TEKS were covered and the students were all engaged. I plan on continuing surveys throughout the year so I can spiral this lesson.

Below is an example of tracking from one of my blogs. The information gathered was about returning visitors. From this information you can easily calculate the degrees of each angle for the percent and number of each category is already given.

		Returning Visits
	84	First Time Visits
	32	1-5 Returning Visits
	10	5-10 Returning Visits
	14	10+ Returning Visits
