May be 100 years ago, when nobody read in a village, school was warranted, but today, esp in cities adn well to do families, literacy rates are high
children learn about alphabets, reading and words even before going to school.
Do we still need any such schools
The logic and common sense
children will learn what they will be presented with in an environment and to observe. And today we live in a world surrounded by letters. From billboards to mobile phones, children read everywhere.
