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 lesson InteGreat (http://www.shodor.org/interactivate/lessons/InteGreat/).
Line of Best Fit (Discussion)
Introduces the line of best fit through the use of scatter plots with outliers.
This worksheet is for use with the Coloring Remainders in Pascal's Triangle activity (http://www.shodor.org/interactivate/activities/ColoringRemainder/).
A discussion about graphing functions in the polar coordinate system.
Introduces students to a geometric derivation of the conic sections.
Learn about how the Pythagorean Theorem works through investigating the standard geometric proof. Parameters: Sizes of the legs of the triangle.
This worksheet is for use with the activity Coloring Remainders in Pascal's Triangle (http://www.shodor.org/interactivate/activities/ColoringRemainder/).
