Activity 2 - Graphing Quadratic Functions using Flikr and GeoGebra

Web 2.0 Tools: http://www.geogebra.org/ and http://www.flickr.com/

Explanation: In this activity, students will identify real world situations where parabolas occur and will search Flikr.com for images that show these situations. They can then import the picture onto the coordinate plane in GeoGebra and set it as the background. Once the image is in the background, students will have to use their knowledge of quadratic graphs to find the equation of the parabola that matches the picture. Students can save the file as a picture or as a pdf to post to a discussion board or wiki.

Here is an Example:

Activity 1 - Ratios and Fractions with Wordle

Web 2.0 Tool: http://www.wordle.net/

Explanation: Wordle,net creates visual expressions of text. The size of the fonts are based on the number of times the word appears in the text.
Here is an example:
Phrase - I love love to teach teach teach math math math math.
Wordle.net word cloud-

Notice that "Math" is the biggest word because it is used the most often in the phrase. In fact, it is 4 times bigger that "I" and "to." So, we can say that "I" is 1/4 the size of "math." Using these ratios, we can allow students to explore ratios and fractions in a visual, interactive, and creative way.
