Bricks
Activity
You are a bricklayer in Southern California (home of earthquakes).
You are required to build a brick wall with no fault lines.
Can you do it? (You may want to use dominoes or other manipulatives
in your search for a solution!)



Chameleon
Graphing–An Introduction to the Coordinate Plane
This is an excellent site from the Math Forum, but some
of the language and graphics are not age neutral. (There are
references to "your parents" and "notes to grownups").
The glossary of terms is excellent. This also is a good family
math website. If you are interested in more coordinate graphing,
go to the algebra learner page. 


Fractals
This wellwritten series of activities is written "for
kids", but these are activities that "adults are free
to enjoy." We think you will, because you’ll learn
all about fractals! If Java is installed on your computer, you
will be able to do these activities online. Otherwise, use paper
and pencil. 


General
Coordinates Game
Plot points in the Cartesian coordinate system or identify the
coordinates of a given point. 


How
Far Is It?
Calculate distance given two coordinates
Is it farther to go from Dallas to New York, or from San
Francisco to Chicago? This site will compute distances (as
the crow flies) between cities around the world. Measurements
are given in statute miles, kilometers, and nautical miles.
You’ll also get compass headings and elevations.



Mathematics
of Cartography
Study the mathematics of maps by using online resources
and great activities. The math problems are about distance,
scale, coordinates, and projections. You’ll be directed
to other websites to complete the activities. 


Pythagorean
Puzzle
This site has an excellent explanation of the Pythagorean
Theorem, with two demonstrations of how it works. One demonstration
is animated and interactive; the second is a paper/scissors
proof. This site also has three problems showing how the Pythagorean
Theorem is used to solve reallife problems. You can find out
something about Pythagoras himself at this website, also. 


Shape
Explorer
Calculate the perimeter and area of shapes on a grid.
