I am really starting to wonder about the received wisdom that parental input is crucial for a child's schooling success? Every politician and every teacher (especially in the state sector) repeats this mantra over and over, and clearly some parental teaching is not going to hurt, but is it really an efficient way of doing things? Most of us are not experts, and end up wasting time finding second rate examples or demonstrating old ways of calculating etc.. Not to mention the inevitable arguments from children who don't wish to be taught by parents. Teachers seem quite happy to assign hours of homework at primary with the cheerful reminder of not to spend more than 20 minutes on it, meanwhile in the school they're doing all manner of arts and crafts, dress-up, cooking, while parents get stuck with the boring sit-down learning.
