I never knew the numbers 1 to 9 could create so much mental energy, or could be so challenging and at the same time great fun. If my arithmetic teachers had that knowledge and if I had been aware of it before now, I would have enjoyed school ten times more than I did and I would never have given up teaching before retirement age.
After my stroke in March of 2013, I was afraid it would impair my mental faculties, so I embarked on developing these number exercises with the numbers 1 to 9, and I had so much fun and excitement, that sometimes I would stay up all night to complete one of these exercises. I use the word exercises because they involve time, commitment, discipline, energy, several though processes, creative thinking and sound cognitive skills, and if you are lacking in any of those features, they will help you to develop them beyond measure.
