Geometry: Spatial Sense and Measurement


Screen shot from siteBricks 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!)

  Screen shot from siteChameleon 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.

  Screen shot from siteFractals
This well-written 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.

  Screen shot from siteGeneral Coordinates Game
Plot points in the Cartesian coordinate system or identify the coordinates of a given point.


Screen shot from siteHow 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.

  Screen shot from siteMathematics 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.

  Screen shot from sitePythagorean 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 real-life problems. You can find out something about Pythagoras himself at this website, also.

Calculate the perimeter and area of shapes on a grid.
