	Description:
Factorize	Learn about factors through building rectangular arrays on a grid.
Factorize 2	Learn about factors through building rectangular arrays on a grid.
Converter	Helps students to convert fractions to decimals and decimals to fractions.
Fraction Pointer	Graphically determine the value of 2 given fractions represented as points on a number line then graphically find a fraction whose value is in between the value of the 2 given fractions and determine its value.
Bounded Fraction Pointer	Similar to "Fraction Pointer" but the user gives the values for the fractional points on the number line rather than having the computer randomly generate them.
Fraction Finder	Similar to "Fraction Pointer" but there is no arrow to help the user determine the value of a fraction between the two endpoints.
Bounded Fraction Finder	The same as "Bounded Fraction Pointer" but there is no arrow to help the user determine the value of a fraction between the two endpoints.
Fraction Sorter	Students represents fractions by coloring in the approptiate portions of either a circle or a square, then order those fractions from least to greatest.
Equivalent Fractions Pointer NEW!!	Visually represent equivalent fractions by dividing squares or circles and shading portions equivalent to a given fraction. Also shows the fractional value on a number line as you color in the fraction.
Equivalent Fractions Finder NEW!	Visually represent equivalent fractions by dividing squares or circles and shading portions equivalent to a given fraction. Also shows the fractional value on a number line after you check to see if your fraction is correct.
Fraction Four	Students play a generalized version of connect four, gaining the chance to place a piece on the board by simplifying a fraction. Parameters: Level of difficulty of fractions to simplify.
Arithmetic Four	A game like Fraction Four but instead of fraction questions the player must answer arithmetic questions (addition, subtraction, multiplication, division) to earn a piece to place on the board. Parameters: time limit, difficulty level, types of questions
Estimator Four	A game like Fraction Four but asks the players to estimate the answer within a given time span. Parameters: time limit, error tolerance, difficulty level
Estimator	Practice estimation skills by determining the number of objects, length, or area. Parameters: error tolerance.
Comparison Estimator	Similar to Estimator but compares two sets of objects.
More or Less Estimator	Similar to Estimator activity but states a quantity and asks the user to estimate whether the set of objects is more or less than the number given.
Venn Diagrams	Students learn about classifying numbers into various categories through answering questions about Venn Diagrams.
Venn Diagram Shape Sorter	Sort colored shapes into a Venn Diagram. Appropriate for elementary grades.
Sequencer	Students learn about number patterns in sequences and recursions by specifying a starting number, multiplier and add-on.
Coloring Multiples in Pascal's Triangle	Students color numbers in Pascal's Triangle by rolling a number and then clicking on all entries that are multiples of the number rolled, thereby practicing multiplication tables investigating number patterns, and investigating fractal patterns.
Coloring Remainders in Pascal's Triangle	Students color numbers in Pascal's Triangle by rolling a number and then clicking on all entries that have the same remainder when divided by the number rolled, thereby practicing multiplication tables, investigating number patterns, and investigating fractal patterns.
Clock Arithmetic	Students learn about modular arithmetic operations through working with various types of clocks. Parameters: Number of hours on the clock.
Caesar Cipher	Students practice simple arithmetic skills by encoding and decoding messages using an affine cipher.

Caesar Cipher II	Students practice simple arithmetic skills by encoding and decoding messages to determine the form for an affine cipher.
Caesar Cipher III	Students practice their reasoning and arithmetic skills by decoding messages to determine the form for an affine cipher.
The Tortoise and Hare Race	Students step through the tortoise and hare race, based on Zeno's paradox, to learn about the multiplication of fractions and about convergence of an infinite sequence of numbers.
Cantor's Comb	Students learn about fractions between 0 and 1 by repeatedly deleting portions of a line segment, also learning about properties of fractal objects. Parameter: fraction of the segment to be deleted each time.
Pattern Generator	Determine and then continue the pattern generated.

Simple Plot	Students can plot ordered pairs of numbers, either as a scatter plot or with the dots connected.
Ordered Simple Plot	Another version of "Simple Plot" which allows the user to plot and connect ordered pairs in the order that they are input. This enables pictures to be drawn by connecting the pairs rather than having the computer connect them from left to right.
Graph Sketcher	Students can create graphs of functions by entering formulas -- similar to a graphing calculator.
Graphit	Students can graph functions and sets of ordered pairs on the same coordinate plane -- similar to a graphing calculator.
General Coordinates Game	Students investigate the Cartesian coordinate system through identifying the coordinates of points, or requesting that a particular point be plotted.
Simple Coordinates Game	Students investigate the first quadrant of the Cartesian coordinate system through identifying the coordinates of points, or requesting that a particular point be plotted.
Maze Game	Students investigate the Cartesian coordinate system by directing a robot through a mine field laid out on the plane.
Simple Maze Game	Students investigate the first quardant of the Cartesian coordinate system by directing a robot through a mine field laid out on the plane.
Function Machine	Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs.
Linear Function Machine	Students investigate linear functions by trying to guess the slope and intercept from inputs and outputs.
Positive Linear Function Machine	Students investigate linear functions with positive slopes by trying to guess the slope and intercept from inputs and outputs.
Number Cruncher	Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule on without at least having two data points.
Whole Number Cruncher	Similar to "Number Cruncher" but only generates multiplication and addition functions to avoid outputting any negative numbers.
Vertical Line Test	Students learn about the vertical line test for functions by trying to connect points in the plane to build a function.
Possible or Not?	Drills students on whether a curve satisfies the properties of functions.
The 2 Variable Function Pump	Students enter two complex numbers (z and c) as ordered pairs of real numbers, then click a button to iterate step by step. The iterates are graphed in the x-y plane and printed out in table form. This is an introduction to the idea of prisoners/escapees in iterated functions and the calculation of fractal Julia sets.

PreAlgebra	Linear Functions/Graphs
Exponential Growth/Decay	Quadratics and Other Conics
Sinusoidal Equations	Sequences

Slope Slider	This activity allows the manipulation of a linear function of the form f(x)=mx+b and encourages the user to explore the relationship between slope and intercept in the cartesian coordinate system.
Function Flyer	A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.
Data Flyer	Similar to Function Flyer, but with the capability of plotting data points as well as a function. Then you can tweak the function to fit the data.
