Applets Used:
Histogram		Students can view histograms for either built-in or user-specified data, and experiment with how the size of the class intervals influences the perceptions. Parameters: Data sets, class sizes.
PieChart		Students view piecharts. Parameters: Number of sectors, size of sector as a percent.
Circle Graph		Enter data categories and the value of each category to create a circle graph. Similar to "Pie Chart" but the user can define the data set.
Bar Graph		Enter data to create a bar graph, then manipulate the graph's maximum and minimum values.
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.
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
General Coordinates Game		Students investigate 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.
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.
Other Software Used:		Microsoft Excel
