I have two kids at Primary and the academic level of teachers is apalling. They can't spell or use proper grammar. They are generally all in the 22 -32 year old age group. The older teachers tend to be better.
There is a lot wrong. Try teaching your kids how to do maths namly multiplication and division. It's all very different than when I learned. I can't see what was wrong with old way. I'm mid 40s.
