Similarly, the value of pi can be approximated by calculating the areas of inscribed and circumscribed polygons. This applet allows for the investigation and comparison of both methods. http://www.merlot.org/merlot/viewMaterial.htm?id=427526 This applet allows students to individually practice working with relationships among fractions and ways of combining fractions. For a two person version of this applet see the Fraction Track E‑Example. http://www.merlot.org/merlot/viewMaterial.htm?id=427840 This resource allows students to investigate, ratios, proportions, area, and perimeter. http://www.merlot.org/merlot/viewMaterial.htm?id=450976 This resource has multiple applets and activities to be used by the students or teacher for discovery, practice, or review of some basic trigonometric concepts such as definition of sine and cosine, graph of sine and cosine, law of sines, law of cosines, and more.
