Coordinate Plane Pictures (2-2 thru 2-8)

This week the Mathletes explored the Cartesian coordinate system in all four coordinates.  Using the x-axis (horizontal) and y-axis (vertical), we can find any unique point in a plane by a pair of numerical coordinates such as (2, 3) which means start on the number 2 on the x-axis and go up three units.Coordinates such as (-3, -6) represents a location at three units to the left of the origin (0,0) and then 6 units down.  This coordinate system was created by Rene Descartes in the early 1600s and further developed by another French mathematician, Pierre de Fermat.

Pop Quiz Clock (1/11/10 - 1/14/10)


For the holidays, I received the Pop Quiz Wall Clock from one of my Mathletes.  It gave me an idea for a lesson where we create a theme for our clock and create the equations or symbols that represent the numbers 1-12.  The number one is 102,413 - 102,412; 2 is the square root of 4; 3 is 198 divided by 66; and so on.


12 Days of Christmas (1/4/10 - 1/7/10)

The song, the 12 Days of Christmas, is a fun (albeit repetitive) song about the gifts given to "My True Love" on the 12 days of Christmas between the birth of Jesus Christ and the Epiphany, January 6th, the day Christians celebrate the arrival of the Magi (Wise Men).  The Mathletes had fun singing this tune, but where is the math?
