Dear Frances,
Just a note of encouragement in the new and intensely interesting domain that you so far have investigated as thoroughly as you have done.
Having watched the steady drop in the standard of mental arithmetic since the worship of electronic calculators flooded thoughtlessly in and seen the corresponding decline in confidence with more advanced mathematics, it is wonderful to come to a lecture where the object is to gain mental agility with a minimum of mental effort.
Your system is very neat and extremely simple and I cannot see why those who embrace it cannot put in front of their students the suggested goal to learn the higher tables - say up to the " x 20" perhaps. You can never have too many recall facts!!!
I've been using your extension methods such as 3 x 17 = 51 so 6 x 17 = 51 x 2 for some time in trying to stimulate students to a wider array of practical skills with common numbers and have been pushing myself to do more and more in the head. I love to play with numbers, so your words "its fun" ring true to my own fun with the subject.
I hope you move from strength to strength with the work you are doing. It is great to see some schools can appreciate your system and use it.
Hopefully, one day, the locals, who as you say, tend to be impressed with a visiting "expert from London", will have the honesty to concede that value in simplicity and acknowledge your discovery.
It is more than time to redeem the lost ground since the calculator swept away common sense in many classrooms.
Thanks again for the opportunity to learn from your lecture.
I really do wish you the rewards your energetic interest justifies you in expecting.
My very kindest regards,
