This worksheet is for use with the lesson Estimating With Fire (http://www.shodor.org/interactivate/lessons/EstimatingWithFire/).
Introduces the notion of using modular arithmetic to encode messages.
Self-Similarity (Discussion)
Discusses how fractals are self-similar objects.
This worksheet is for use with the Hilbert Curve Generator activity (http://www.shodor.org/interactivate/activities/HilbertCurve/).
Estimator Four (Activity)
Play a "Connect-Four" style game, earning a game piece each time you answer an estimation question correctly. This game asks the players to estimate the answer to addition, multiplication, and percentage questions. Choose difficulty level, question types, and time. Estimator Four is one of the Interactivate assessment games.
This worksheet is for use with the Hilbert Curve Generator activity (http://www.shodor.org/interactivate/activities/HilbertCurve/).
Looks at how irregular fractals can be generated and how they fit into computer graphics.
Introduces all of the 2 variable function and prisoner/escapee notions necessary to understand the Mandelbrot set.
Inverse Properties (Discussion)
Introduces the concepts of the additive inverse and multiplicative inverse and how they are used when solving equations.
Step through the generation of Sierpinski's Triangle -- a fractal made from subdividing a triangle into four smaller triangles and cutting the middle one out. Explore number patterns in sequences and geometric properties of fractals.
