Sequences and Series

Henri Picciotto

visual arithmetic series

Staircases: a lesson which can work in different ways and yield different payoffs at various levels: pre-algebra, Algebra 1, Algebra 2, Teachers' Mathematics. I link to it here because it can serve as a preview of arithmetic series. (There are detailed notes and some spoilers on pp. 2-3.)
