"Alice in Mathland"
"Donald Duck in Mathematics Land"
"The Line and The Dot"
"The Ink is Black, The Page is White"
"The Red Balloon"
"Free To Be You and Me"
I'm pretty sure there was at least one other Donald Duck film, but it was narrated by the professor duck and Donald was kinda the example. I think it was a history one because I recall caveduck Donald and Donald in a toga.
Any other films you remember from school? Not school age, but actual class time spent.
