What is Numerical Acumen?

Our aim is simple: to help you to develop the mechanical basics of a numerical mind in each of your students:

  • Increase the speed at which they recall basic number facts and other mathematics facts.
  • Improve their accuracy when using their brain as a calculation device.
  • Improve their speed when using their brain as a calculation device.
  • Improve their understanding of when not to, and when to, use an electronic calculator.

Support is offered through two different avenues:

  1. Online instruction, practice and assessment.
  2. Paper-based instruction, practice and assessment.


Your students have 24-7 access to Numerical Acumen's game-based practice and assessment environment.
Try out the single-player and multi-player games.

Students' progress is logged and can be viewed on easy to read graphs.
View examples of the overall play time and score/stage graphs.

Numerical Acumen is a marathon, not a sprint.
It is a program for students at all points of their development.
