A good teacher must have a higher level of understanding of the concepts
being introduced at a lower level to ensure that no misleading ideas are
introduced through over simplification.
Best wishes!

Hi. Please be aware that we're not interested in explaining math theory.
The children we are targetting are in the 7 to 10 age group, and the main
purpose of our software is to introduce mathematical concepts, the
difference between odd and even numbers being just one such concept.
Cheers!
