I have not yet had the chance to teach at Harvard but look forward to teaching (likely) math 1b in winter 2021. 

For the past three years, I have taught grades 6-9 math at the Limmud Centre, an innovative homeschooling centre for children from the Lubavitch community. They have been working together with the Quebec government to push the limits of what effective and coopoerative homeschooling can look like.
