I don't have a child yet, but if I do I'd want him to be able to do basic algebra at around that age, let alone reading, which he or she would, obviously have to be at an adult level for. I like how you keep alive the illusion that a child could play at some point in their life; as if.
People assume so much. You don't have to be a Tiger Mom to teach your kid how to read. You just have to keep exposing them to it over time slowly. Its a trivial time investment which empowers them to explore their own interests independently.
I didn't say "no playing until reading is done" I said "no video games until reading" is done. This was because I was concerned with the amount of video games he was playing.
This rule provided a way for him to self regulate his game time, and on the days he does play video games, at least he spent some time expanding his mind.
