I’ve been thinking this over today. DS recently went to a Kumon class (if you trawl through Mn threads over the years this is generally much hated on MN). All the kids coming out were Indian or Chinese, all the kids in her group Indian or Chinese. A smattering of black children and 1 white child (DS). DS won’t be going back (it was a trial class) because it just seemed to be repetitive rote learning of hundreds of sums, but clearly this is working somewhere along the line?
