Manipula Math Applets.
There are nearly 300 applets found in this site for middle school
students, high school students, college students, and all who are
interested in mathematics. The applets are very interactive, and
mathematical topics include applets for middle school students,
calculus, vectors, trigonometry, complex numbers, conics, and various
other topics.
Geometry
Applets. This site provides over 100 geometry applets.
They are conveniently categorized by level (easy, intermediate, and
advanced). The applets relate to such topics as area, volume,
angles, and the Pythagorean Theorem.
Algebra
Factoring
a trinomial. This
applet allows students to have practice factoring expressions of the
form ax^{2} + bx + c.. It gives them an expression and
then gives them up to four hints. If they cannot find an answer,
it gives the answer.
Graphing
Linear Equations.
This site allows you to graph a variety of different functions at the
same time. It is like a graphing calculator in some ways. You can graph
up to 6 different functions at the same time. It says that this plotter
"can plot functions, differentials and integrals, including
trigonometric functions. Use this to help with your algebra,
trigonometry or calculus homework."
Newton's Applet. This applet allows
for you to find numerical solutions to equations in one variable. You
simply type an equation in the "Equation box" and click on "solve for X
or Y," and your solution is shown.
Slider
Graph. This applet allows you to graph various quadratic and
linear functions and then manipulate the constants to determine their
effects on the graph.
Balance
Beam Algebra. This applet lets you solve various linear
equations by balancing blocks on a balance beam. It does take a while
to open.
Function and Derivative Plotter. This applet plots a function
of one variable and/or its derivative. You can set the names of the x and y axis variables by clicking "Draw
Frame." Then, you enter the function in the "y =" box. Lastly, you click "plot
function" and "plot derivative," and these will be plotted. You can
change the colors too if you wish.
Geometry
Geoboard.
Using this 16x16 virtual geoboard you can add as many rubber bands as
you wish and you can color in the areas created by the rubber band.
The Sum of Outer Angles of a Polygon.
This applet cleverly demonstrated a way to see that the sum of outer
angles of a polygon add up to 360 degrees.
Snail Shell. This applet works with
proportions in a very interesting way. When a snail grows up, it makes
its room in the shell. The size of new room is k times as large as adjacent room,
and the students are able to manipulate the shell and see how
proportions work.
Surface Area and Volume. This is a
website on volume and surface area. It allows you to change the width,
depth, and height of a rectangular prism and triangular prism. The
applet shows how the volume and surface area change with each changed
dimension. It also lets you move the figures around and look at them
from different viewpoints.
Triangle
Calculators.A collection of four
applets that calculates the lengths and angles within a triangle given
3 sides, 2 sides and the included angle, 2 sides and the non-included
angle, or two angles and the included side.
Polygon
Creator. This applet allows you to create a wide variety of
regular polygons by entering in angles and the length of the sides.
Interactive
Geometry. This site contains numerous interesting,
interactive geometry applets,
mainly geared towards understanding the fundamentals of Euclidean
geometry.
Spinner. This is an online spinner.
With this you can study the probability of events and it automatically
records your results.
Puzzles
Tangram
Java Applet. Fit seven geometric pieces together to form
different shapes.
Magic
Squares Applet. Place numbers 1-16 in a 4x4 grip so that each
row, column, and diagonal sum to 34.
Statistics
Guessing
a line of best fit. This applet allows a person to add up to
50 points onto its green viewing screen. A red line appears on the
screen and the person can use the slider on the right to rotate this
line until they think it is the best fit. The computer will also
calculate a line of best fit and you can see how close you were.
Trigonometry
Sine,
Cosine and Tangent of an Angle. This applet allows students
to pick the angle of the circle, and see it graphed on the Sine,
Cosine, or Tangent curve.
