Unschooling Resources: Algebra
Algebra
in Simplest Terms
An Annenberg Media project at learner.org. These 26 half-hour online
videos are free. "In this series, host Sol Garfunkel explains how
algebra is used for solving real-world problems and clearly explains
concepts that may baffle many students. Graphic illustrations and on-location
examples help students connect mathematics to daily life. The series
also has applications in geometry and calculus instruction." (post

Common
Algebra Mistakes
"Find the algebra mistakes in these examples and read plain language
explanations so you can avoid making these same mistakes!"
CoolMath
Algebra
"Bored with
Algebra? Confused by Algebra? Hate Algebra? Yeah, we can fix that. Coolmath
Algebra has hundreds of really easy to follow lessons and examples that

Figure
This!
A listing of the algebra-related problems in the Figure This! archive.
These activities and brain teasers are ultra-cool and fun for the whole
family.
Fun
with Calendars
"Take any calendar. Tell your friend to choose 4 days that form
a square like the four to the right. Your friend should tell you only
the sum of the four days, and you can tell her what the four days are.
How does the
puzzle work? You know how people always want to see a use for algebra?
Well this puzzle uses algebra."
The
Hot Tub
Users answer questions based on a given graph. Creative and great for
discussion (and general silliness!). If you like this, check out more
of Cynthia Lanius's fun
math problems.
Interactive
Algebra Activities
Lots of Java-based activities covering algebra and pre-algebra concepts.
Maze
Game
"This (Java) activity allows the user to practice their point plotting
skills by having them move a robot through a mine field to a target
location." Pretty cool, really.
Mystery
Operations
"In this activity the computer makes up a mystery operation, and
you have to figure out what the operation is. You give the computer
two numbers to calculate, and it tells you the answer. This is your
first piece of evidence. Need another clue? Then gather more evidence."
It may take a
moment for the answers to appear.

Show
Me the Steps
"Practice solving linear equations with Show Me the Steps applets
from StudyWorks.... Step by step problem solving lets you move backwards
or forwards through the simplication and solving routines while learning
good algebraic techniques and notation as you go."
Visualizing
an Infinite Series
A great visual representation.
