Interactive Java-based applets (some game-like) to practice/test proficiency on scores of math

Algebra 1
Percent Change

A static worksheet for calculating the percent change of grocery prices over the years. I have used
a modified version of this (where students guess the prices before calculating the change) as a
lesson opener.

Hippocampus
http://www.geneyang.com/factoring/
A comic strip version of factoring. Includes primitive remediation. Intro and 5 lessons including
GCF, Distributive Property, Trinomials, & Factoring by Grouping. Corny but clear explanations
with extra examples if needed.

Step by step animated lessons arranged by textbook and topic.
Algebra 1
Geometry
MathNets
http://www.mathsnet.net/
A lot of interactive lessons for Algebra & Geometry. It is not a US site, so there are some
terminology differences (like "factorising") but otherwise, it has possibilities. The Geometry portion
seems more comprehensive, especially for an Applied class, but it may duplicate the functionality
of SketchPad (don't know since I don't teach Geometry). It does have a learning curve to do the
constructions however.
Algebra 1

http://www.econedlink.org/lessons/index.cfm

Looks at how military strength has changed based on the economy. Some links for additional
exploration, although I just use the first part (skipping the economics lesson) as a static practice
worksheet.
Algebra 1

9-12 actvity. Students write & solve a system of linear equations in a real-world setting. Students
should be familiar with finding linear equations from 2 points or from slope & y-intercept. Graphing
calculators not necessary for this activity but could be used to extend the ideas found on the
second activity sheet. Non-interactive.

GeoGebra
http://www.geogebra.org/cms/
GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins
geometry, algebra and calculus. You can do constructions with points, vectors, segments, lines,
conic sections as well as functions and change them dynamically afterwards. On the other hand,
equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with
variables for numbers, vectors and points, finds derivatives and integrals of functions and offers
commands like Root or Extremum. These two views are characteristic of GeoGebra: an
expression in the algebra window corresponds to an object in the geometry window and vice
versa.

Let's Make a
Deal
http://www.stat.sc.edu/~west/javahtml/LetsM
akeaDeal.html
As a motivating example behind the discussion of probability, an applet has been developed which
allows students to investigate the Let's Make a Deal Paradox. This paradox is related to a popular
television show in the 1970's. In the show, a contestant was given a choice of three doors of which
one contained a prize. The other two doors contained gag gifts. After the contestant chose an
initial door, the host then revealed an empty door among the two unchosen doors, and asks the
contestant if he or she would like to switch to the other unchosen door. The question is should the
contestant switch. Do the odds of winning increase by switching to the remaining door?
