Power or lack of it

I think we should all keep a log of power outages showing the time and the class/grades missing lessons. We must make sure that when we have power we WORK. Somehow we must have a supply of suitable paper based exercises that the learners can do in class when we have no power. I have told mine that if they are considering buying a computer for home, it should be a laptop which can be charged and always have 2 hours of available power. We will have to plan how we are going to run tests, and the power goes down. And exams when we have two sessions! Oh dear, I had not thought of this!
Luckily we have our textbooks and the learners can use them, especially the Gr 12 book which has many many good written exercises.
We must also make sure that work is saved on the network AND on a flash drive/removable hard drive so that we can work on it at another place or on a laptop which has power.
