Introduces the basic ideas needed for understanding functions.
Sample triangle drawn on a coordinate grid for use with the Ordered Simple Plot Activity (http://www.shodor.org/interactivate/activities/OrderedSimplePlot/).
This worksheet is for use with the lesson Algorithm Discovery with Venn Diagrams (http://www.shodor.org/interactivate/lessons/AlgorithmDiscovery/).
Learn about how the Pythagorean Theorem works through investigating the standard geometric proof. Parameters: Sizes of the legs of the triangle.
Recursion (Discussion)
Discusses the idea of recursion as it pertains to fractals and sequences.
This worksheet is for use with the Coloring Multiples in Pascal's Triangle activity (http://www.shodor.org/interactivate/activities/ColoringMultiples/).
Polar Coordinates (Discussion)
A discussion about what the polar coordinate system is and how to graph a point in this system.
Ordered Simple Plot (Activity)
Plot ordered pairs on the graph, and they will be connected in the order that they are input. This enables you to decide how the pairs should be connected, rather than having the computer connect them from left to right.
Calculate the length of one side of an automatically generated right triangle by using the Pythagorean Theorem, and then check your answers. Pythagorean Explorer is one of the Interactivate assessment explorers.
This worksheet is for use with the Vertical Line Test activity (http://www.shodor.org/interactivate/activities/VerticalLineTest/).
