Coordinate Geometry Curriculum
A plate from the Coordinate Geometry Curriculum

Touch Graphics has created a short, fully interactive program for teaching subjects that are important as an introduction to the study of Calculus.  

  • Material that is covered by this brief curriculum includes discussion of the features of a coordinate grid; use of Pythagorean Theorem to calculate the distance between any two points; delta notation; equations of lines; and slope. 
  • The curriculum includes a sequence of tactile digrams that are produced on five overlay sheets which fit on the TTT device.
  • This application has undergone user testing by a group of visually impaired students.
