NumberShark V5 is most often used by students between 6 and 15. Most games are appropriate for any age although a few of the games are more suitable for younger children.
Older students, with reasonable number skills, use Numbershark to improve their mental maths - sometimes before exams.
The program addresses many of the difficulties which lead students to dislike maths. These include poor short term memory, limited attention span and poor sequencing skills.
To help those with dyslexia and dyscalculia, many of the games give a visual idea of what is happening when you add, subtract, multiply or divide. Fractions and decimals are also shown visually. Variable speeds and other options meet all grades of skill.
