Every evening after dinner, Herman Agbavor and his 5-year-old son, Herbert, have a ritual. Little Herbert climbs into his dad's lap, unzips his book bag and they go over his kindergarten homework.
The two of them have been doing some variation of this homework routine since Herbert was 1. That's when Agbavor first enrolled the boy in preschool.
They live in a working-class neighborhood of Ghana's capital city, Accra — in a cement block apartment in a multifamily house that has a television and lots of books but no indoor plumbing.
