I finally grabbed a piece of paper I found and started writing:
100+80 (80X1/2 =40) =140And yes, after that they caught on to what I had been trying to communicate. I explained to one of my young fellow sales people that I had been a remedial teacher. I honestly believe that those talents, skills and experience really help me with some of the customers.
100+100 (100X1/2 =50) =150
When one method doesn't work, I try another. I did that when teaching EFL to small groups. As long as there is basic intelligence there will be a method that suits. Today's teaching, at least here in Israel, is based on the very expensive and rigid workbook. The "experts" claim that it's good that the children can progress at their own pace, but there is very little real teaching. Not everyone's mind suits those workbooks. Some people need to hear the concepts and facts repeated in different ways orally, and workbook learning is not oral. Workbook teaching isn't flexible either. I would have been a total failure and trouble-maker in today's classroom.
I learn best with discussion. I use that when I give my Tanach, Bible classes to my friends. If any of my grandchildren are like me, they're in trouble.
