Mayan Numbers: Base 20 Number System vs. Base 10

The Maya number system is very different from the system you use daily—the Maya used only three symbols to represent all numbers! They used a dot to represent 1, a line to represent 5, and a shell to

AREA OF TRIANGLES AND RECTANGLES

A logical extension to our triangle coordinates and classify game was finding the area of triangles.

TRIANGLES: PLOT COORDINATES AND CLASSIFY GAME

After the Mathletes became experts at plotting coordinate points in either 1 or 4 quadrants, I created a game that would allow them to plot three points to create a triangle and then classify it as either acute, obtuse, or right and then classify it as either scalene or isosceles.

Coordinate Plane Pictures: Eagle, Homer, Bugs Bunny and much more

The most important three factors in real estate (buying property) is location, location, location. The same is true of coding images on a computer. Every pixel has a specific location ordered by a horizontal (x) and vertical (y) axis.

Preparation and Actual International Contest

Each child followed my best practices by completing all or most of the 20 questions in the practice test, self-graded and identified the few questions that they still wanted to master. We spent the first part of class reviewing these problems and my best practices approach.
