My cousin who is a 2nd grader spends 0 hours studying and rarely has any homework (about one 10-item worksheet every 2-3 months). She studies at a Montessori school and has 5 days of classes a week. Her school hours are 9 am to 3 pm and she doesn't bring any books nor does she wear a uniform. Her syllabus does enumerate Basic Geometry as one of her subjects but from what we've observed she spends more than half the time playing with her classmates. This is because Montessori method believes that hands-on activity yields better results.
