NCTM's Illuminations
In April of 2009 NCTM's Illuminations launched a new site called Calculation Nation.  Have any of you had the opportunity to check out this new site?

Calculation Nation™ allows students to challenge opponents from anywhere in the world. At the same time, students are able to challenge themselves by investigating significant mathematical content and practicing fundamental skills. The element of competition adds an extra layer of excitement.

Calculation Nation™ currently features the following five games:

·        Square Off                   Players use area and perimeter in this game to “capture” alien space ships.  The more ships you capture and the more area you cover, the more you score.

·        Factor Dazzle    In this game, players are to find all the factors of a number to earn points.  Then choose a number for you opponent to find all the factors.

·        Fraction Feud   Earn points by creating a larger (or smaller) fraction than your opponent.

·        Times Square   Try to get four squares in a row vertically, horizontally, or diagonally by using knowledge of factors and multiples.

·        Slam Ball            Contestants use their knowledge of angles, symmetry, and reflections to choose the path that will result in the most points.

These games provide an entertaining environment for students to explore mathematics. They are a great way for students to reinforce skills that they have learned in class.  The games are organized around content from the upper elementary and middle grades math curriculum.  The folks at NCTM keep track of scores and let students see a map featuring the states where their opponents live.  No names are revealed--just states and screen names.  I highly recommend Calculation Nation™ and hope that you will check it out  at if you haven’t already! Let us know what you think by posting comments below.

Welcome to the KEDC Math Blog!
Hello, fellow math teachers!  I have met several of you in math professional development sessions we have had here at KEDC over the past 3 years.  I am happy to let you know that I have become a full-time math consultant here at KEDC and plan to use this blog to keep in touch with each of you by sharing information that may be helpful to your teaching or to your students.  I would also like for you to use this blog to network with other teachers in our cooperative.  Sometimes it feels that we are all alone in our classrooms, so perhaps this will enable us to collaborate.  I hope that you are off to a great start this school year!  On September 2, Tonya Evans, Cathy Pennington, and I will have our first math cadre.  If you will be able to attend please email me at and let me know.  Hope to see you on September 2nd.
