Fraction Quiz gives the user randomized questions to answer on simplifying fractions; conversions between fractions, decimals, percents, and percentage problems.
Represent fractions by coloring in the appropriate portions of either a circle or a square, then order those fractions from least to greatest.
Students generate complicated geometric fractals by specifying starting polygon and scale factor.
Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs.
General Coordinates Game:
Students investigate the Cartesian coordinate system through identifying the coordinates of points, or requesting that a particular point be plotted.
Students can create graphs of functions by entering formulas -- similar to a graphing calculator.
Students can graph functions and sets of ordered pairs on the same coordinate plane.
Linear Function Machine:
Students investigate linear functions by trying to guess the slope and intercept from inputs and outputs.
Students learn about sampling with and without replacement by modeling drawing marbles from a bag. Parameters: Number and color of marbles in the bag, replacement rule.
Students enter data and view the mean, median, variance and standard deviation of the data set. Parameters: Number of observations, range for observations, which statistics to view, identifiers for the data.
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.
Determine and then continue the pattern generated.
Students are shown shapes on a grid after setting the area and asked to calculate perimeters of the shapes.
Students view piecharts. Parameters: Number of sectors, size of sector as a percent.
Students click to build dot plots of data and view how the mean, median, and mode change as numbers are added to the plot. Parameters: Range for observations.
Positive Linear Function Machine:
Students investigate linear functions with positive slopes by trying to guess the slope and intercept from inputs and outputs.
Students find the length of a side of a right triangle by using the Pythagorean Theorem, and then check their answers.
Racing Game with One Die:
Two players each roll a die, and the lucky player moves one step to the finish. Parameters: what rolls win and how many steps to the finish line.
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.
Students can plot ordered pairs of numbers, either as a scatter plot or with the dots connected.
Students can create a game spinner with one to twelve sectors to look at experimental and theoretical probabilities.
Surface Area and Volume:
Students manipulate dimensions of polyhedra, and watch how the surface area and volume change.
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.
Whole Number Cruncher:
Similar to "Number Cruncher" but only generates multiplication and addition functions to avoid outputting any negative numbers.
