6 1-hour periods, plus (optional) breakfast and lunch
4 1.5-hour periods, plus (optional) breakfast and lunch

Breakfast is the fuzzy period, where you get in early so you get to hang out with friends and get fed.

Breakfast and lunch often cost less than $2 each. Public school can function as absurdly cheap daycare *with meals*, so parents are strongly incentivized to go for it.
