**DESMOS CLASSROOM ACTIVITIES
**

I began using the Desmos graphing calculator with my students at Maryknoll in 2012 and am totally hooked. 🙂 This year, I’m thrilled to be a Desmos Fellow! I spent Veteran’s Day weekend at Desmos headquarters with a fantastic group of math educators, exploring and learning about Desmos. Great weekend, and I got more Desmos socks.

**3-ACT MATH TASKS**

My own adventure with 3-Act Math Tasks began when I saw Dan Meyer’s TED Talk, Math Class Needs a Makeover. Since then I’ve been using 3-Act Math Tasks to engage students and explore mathematics, and the past two years I’ve been supporting K-12 teachers in this work through professional learning and in-classroom coaching.

**COMPARING QUANTITIES for Grades 5-11**

Comparing Quantities (qualitative comparisons) is a classroom routine that make student thinking visible and supports the Standards for Mathematical Practice. It can be used at any grade level and with a wide range of content.
