I was invited by the San Francisco Teachers’ Math Circle to present some problems. Here’s the basic info.

**When**: Tuesday, May 1 at 6:00 PM

**Where**: Trailer P (behind Thorton Hall) at San Francisco State University

3699 19th Avenue, San Francisco, CA

As far as I know, the event is free, and dinner is included!

I will present a pattern blocks-based problem which will be familiar to people who have taken my Visual Algebra workshop. (But it’s a problem one can revisit, as there are lots of solutions!)

If there’s time, we’ll follow up with additional problems drawn from

*Algebra: Themes, Tools, Concepts,*and*Geometry Labs.*I have chosen problems that are accessible to students, at one level, but where there’s more to find out at a teacher level. If you haven’t heard me talk before, this would be a good opportunity to get acquainted. I hope to see some of you there!
