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:
- Online instruction, practice and assessment.
- Paper-based instruction, practice and assessment.
Numerical Acumen is a marathon, not a sprint.
It is a program for students at all points of their development.
