Sierpinski's Carpet (Activity)
Step through the generation of Sierpinski's Carpet -- a fractal made from subdividing a square into nine smaller squares and cutting the middle one out. Explore number patterns in sequences and geometric properties of fractals.
Impossible Graphs (Discussion)
Shows what makes a graph represent impossible situations and how to avoid these problems.
This worksheet is for use with the Pythagorean Explorer activity (http://www.shodor.org/interactivate/activities/PythagoreanExplorer/).
This worksheet is for use with the Caesar Cipher III activity (http://www.shodor.org/interactivate/activities/CaesarCipherThree/).
Derivate (Lesson)
Explores derivatives and the idea of infinity using a geometric interpretation of slope.
Scatter Plot (Activity)
Graph ordered pairs and customize the graph title and axis labels. Points are connected from left to right, rather than being connected in the order they are entered.
This worksheet is for use with the Caesar Cipher activity (http://www.shodor.org/interactivate/activities/CaesarCipher/).
This worksheet is for use with the Scatter Plot activity (http://www.shodor.org/interactivate/activities/ScatterPlot/).
This worksheet is for use with the lesson Solving Equations (http://www.shodor.org/interactivate/lessons/SolvingEquations/).
