Finlay McQuade, Boğaziçi University, Turkey, presents these strategies for solving problems:

  • Draw a Diagram

McQuade illustrates each strategy with sample math challenges and solutions by students. The site is available in English and Turkish.


Engauge Digitizer

http://digitizer.sourceforge.net/

Mark Mitchell's open source, digitizing software converts an image file showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot.

The numbers can be read on the screen and written or copied to a spreadsheet. The process starts with an image file containing a graph or map, with the final result as digitized data that can be used by other tools, such as Microsoft Excel and Gnumeric.
