Base Ten (Discussion)
Discusses the base ten system and how it differs from other base number systems.
Shows how modular arithmetic can be thought of as clock arithmetic.
Determine the value of a given fraction represented as a point on a number line. Then find a fraction whose value is a given fraction. Fraction Pointer is one of the Interactivate assessment explorers.
Multi-Step Functions (Discussion)
Discusses the notion of composite functions as several "number machines" with the output of one machine becoming the input of another.
Two Variable Functions (Discussion)
Introduces 2 variable functions as ordered pairs and how to operate perform operations on ordered pairs.
Algorithm (Discussion)
Introduces the concept of algorithms and how algorithms affect mathematics.
Recursion (Activity)
Graph recursive functions by defining f(0)=C and defining f(n) based on f(n-1).
This worksheet is for use with the Sierpinski's Triangle activity (http://www.shodor.org/interactivate/activities/SierpinskiTriangle/).
Flake Maker (Activity)
Create your own fractals by drawing a "line deformation rule" and stepping through the generation of a geometric fractal. Parameters: Grid type, number of bending points on the line.
This worksheet is for use with the Mandelbrot Set activity (http://www.shodor.org/interactivate/activities/TheMandelbrotSet/).
