After teaching HS math for over 30 years, I now support math teachers K-12 as Co-Director of the Bay Area Mathematics Project, which is based at The Lawrence Hall of Science, a children's science museum on the hill behind the UC Berkeley campus. So of course, I'm especially interested in good apps for learning math. My hobbies are gardening and rehearsing and performing with The Jubilee American Dance Theatre, which rehearses at Ashkenaz in Berkeley.
