# 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.
