Using Maps in an Elementary School Math Lesson
When it comes to creative uses of Google tools, Tom Barrett is certainly a leader that we can all learn from. A great example of this can be found in Tom's Math Maps. Math Maps are Google Maps on which Tom and others have created placemarks which when clicked reveal mathematics questions for students to answer based on the maps. There are questions available for every elementary school grade level. The placemarks are color-coded to indicate the level of the questions. Blue = Kindergarten, Red = 1st grade, Green = 2nd grade, Light Blue = 3rd grade, Yellow = 4th grade, Purple = 5th grade.

Cairo Tiling - David Bailey's World of Escher-like Tessellations
Stop Press 6 June 2016: The Cairo tile designer has been found, one Ramzi Omar, an architect. More details to follow. The first purposefully published in situ pictures of the two types of Cairo pentagon tiling? © Helen Donnelly Figure 1, Cairo, Outside Behoos Metro Station, Figure 2 In various books and articles on tessellation, a reference to a pentagonal tiling known as the ‘Cairo Tiling’ (or similar, such as ‘Cairo pentagon/tessellation//paving’) is commonly to be found (with descriptions such as ‘frequently seen’ and ‘many of the streets are paved…’), said to be found in Cairo, Egypt, hence the title.
Fun Kids Online Math Games
"Sheppard offers everything from early math to pre-algebra. The lessons include interactive activities to practice concepts. Students can shoot fruit, pop balloons, and even play math man (the math version of pac man!).

Polymaps - Pavement Quality
This example also uses a data visualization library called Protovis for color interpolation. Protovis is optional and not required to use Polymaps. Note that we’re not using Protovis to render anything—just data processing. Source Code
Example 1: The Natural Base
Plotted below are two familiar exponential functions: and On the interval shown, we see that 2x begins with a slight head start in value, but 3x quickly outgrows it, overtaking 2x at We also see that the larger the values of each function, the faster they grow. Said geometrically: Both curves are steeper the further up you go.

Resources for Teaching the Math & Science of Sports
The Super Bowl is coming up this weekend and many classrooms will have students buzzing with their predictions for Sunday's game. This provides a good opportunity to incorporate math and science with sports. Below is a re-publishing of a review I wrote two years ago about NBC's Science of Football lesson materials.
