Similar to "Number Cruncher" but only generates multiplication and
addition functions to avoid outputting any negative numbers.
Angles
Students practice their knowledge of acute, obtuse and alternate angles.
Area Explorer
Students are shown shapes on a grid after setting the perimeter and
asked to calculate areas of the shapes.
Clock Wise
Practice reading a clock.

Students manipulate dimensions of polyhedra, and watch how the surface
area and volume change.
Algebra Four
Students play a generalized version of connect four, gaining the chance
to place a piece on the board by solving an algebraic equation.
Algebra Quiz
Similar to Algebra Four, Algebra Quiz gives the user randomized
questions to answer on solving algebraic linear and quadratic equations
of one variable.
Fraction Quiz
Fraction Quiz gives the user randomized questions to answer on
simplifying fractions; conversions between fractions, decimals,
percents, and percentage problems.
Function Flyer
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.
Function Machine
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.
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.
Linear Function Machine
Students investigate linear functions by trying to guess the slope and
intercept from inputs and outputs.
Ordered Simple Plot
nother 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.
Positive Linear Function Machine
Students investigate linear functions with positive slopes by trying to
guess the slope and intercept from inputs and outputs.
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.
Simple Plot
Students can plot ordered pairs of numbers, either as a scatter plot or
with the dots connected.
Dice Table
Students experiment with the outcome distribution for a roll of two dice
by playing a dice throwing game. Parameters: Which player wins on which
rolls.

Experiment with experimental probability using a fixed size section
spinner, a variable section spinner, 2 regular 6-sided number cubes or
design your own number cubes. Appropriate for elementary grades.

drawing marbles from a bag. Parameters: Number and color of marbles in
the bag, replacement rule.
Racing Game with One Die

finish. Parameters: what rolls win and how many steps to the finish
line.
