A couple of days from now - January 6 - is the 100th anniversary of Maria Montessori opening her first school.
That school, in Rome, is still open. There's having a big conference there to celebrate. My wife is there, too, helping to ring in the centenary.
I put "preschool" in quotes only because Montessori teachers don't like that expression. It's not pre-school. It's school. Period.
School for the very young, yes,
But truly school, nonetheless.
