Geogebratube Applets

Exterior Angles of Polygons This applet uses the metaphor of a car driving around a track to illustrate the idea of exterior angles. I like it because it allows you to change the polygon and experiment with different shapes and sizes of polygons.

Equivalent Fractions This applet allows the user to change the numerator and denominator of a fraction and then simplifies the fraction if possible. I find it interesting because of the animation it provides when simplifying fractions; because of the colors, it's easy to see why the fractions are equivalent.

Triangle Paradox This applet demonstrates the triangle paradox. By cutting a right triangle into these specific shapes and rearranging them, we come up with two different areas for the same size triangle. I like this applet because I love this paradox. Although I dont' know how it works, I think it would be an interesting discussion topic in a classroom.

Shading Venn Diagrams This applet allows you to experiment with unions and intersections without having to draw hundreds of Venn Diagrams on the board. I find it interesting because it allows the user to check their answer to 14 different combinations of unions and intersections to check their understanding.

Surface Area for Cuboid This applet uses the net of a cuboid to demonstrate surface area. I like this applet because the user can change the dimensions of the rectangular prism, animate the net folding up, and let's you check your answer.

Applets

Adding Fractions: This applet gives a visual representation of getting a common denominator and adding fractions.

Riemann Sums: This applet allows you to change the width of Riemann rectangles to more closely approximate the area under the curve.

Adjustable Spinner: This applet gives the user the ability to adjust the theoretical probabilities of a spinner and then calculate the experimental probability.

Pascal's Triangle: This applet allows you to recognize patterns in Pascal's triangle by selecting different rules for coloring.

Sum of Angles in a Triangle This applet demonstrates that the sum of the angles in a triangle add up to 180.
