You don't need to teach them at home at all.
You do need to have an interest in them as a person.
You do need to teach them some independence in where their belongings are, whether or not they need glasses in school
You need to teach them resilience to get along with others around them.
You need to teach them manners so they don't call out.
You need to make sure they are fed/dressed/clean
You need to stop having adult conversations about adult decisions in their hearing (tough one I know).
You need to make sure they are at school on time most of the time.
If these were done at home. I could concentrate so much more time on actually teaching them the curriculum.
A bit of reading/spelling support/maths practice of times tables etc. Would be amazing.
This is at a Primary level obviously.
