It will be very interesting to see what the state of education is when all the kids finally return to school! How long will it take for teachers to absorb all the interesting ‘old school’ concepts that kids were exposed to when the parent or grandparent was the teacher!
For example, how long ago did you learn arithmetic – how to add, subtract, multiply and divide numbers?
In my day, addition used a concept that is now called Column Math. Numbers were ‘stacked’ on top of each other. First you added the numbers in the far right column… well, you probably know the rest about what gets carried over to the next column.
