Amy Bowden – My name is Amy Bowden and I am a high school math teacher in Baltimore, MD. I have been teaching high school math for 3 years and am currently pursuing my MAT. I was lucky enough to participate in CPM’s Academy of Best Practices in 2018 and currently serve as a teacher researcher through CPM’s Teacher Research Corps. I have an eccentric teaching style that involves a great deal of humor, collaboration, inquiry and discussion. I have a passion for mathematics and am determined to make math achievable for all learners. I am looking forward to my team’s research this school year! 

Angela Kraft  – My name is Angela Kraft and I’m an Instructional Specialist and Math Coach in Oconomowoc, WI.  I have been teaching middle school math for 15 years. My passion as a math educator is to help students grow a love for learning and solve problems to help prepare students for the world beyond high school and college. My personal pedagogy involves collaboration among peers and allowing students to tackle problems through discovery rather than direct instruction. This type of teaching allows students to learn from one another, learn to ask questions, justify their thinking, and learn to work in a team. Through this type of math education, hopefully, in a few years, we will hear fewer adults say, “I am not a math person.”

Brooke Raven-Sandberg – I have been teaching high school math in Fortuna, CA for the last 9 years. I am currently teaching Algebra 2 and Geometry using the CPM curriculum. I enjoy the challenge of getting students to work together as they develop their math skills.

Karen Kurcz – I am Karen Kurcz and I teach at Chelsea High School in Chelsea, Michigan. I have been teaching high school math for over 26 years, and this is my third year with CPM. I feel that bringing CPM and my TRC research into my classroom has made me a far better teacher and has made my students even better learners!  Through the years, my husband, Mike, and my four beautiful, grown children have been my greatest gifts and support.

Kathryn Hayes – I am Katie Hayes, and I am in my 7th year of teaching! I’ve taught CPM for 4 years, and this is my second year in TRC. My research team is focused on investigating the impact of feedback on the student.

Laura Bell I have been teaching middle school for 13 years. I spent 7 of those years teaching predominantly social studies before switching to teaching 8th grade math and algebra using the CPM curriculum. This year I took a new job teaching 6th and 7th grade math using the CPM curriculum. The opportunity to teach CC1 through CCA has given me a perspective of the connections that the CPM curriculum provides. I am in my 4th year as a CPM TRC researcher. This has given me the opportunity to collaborate with math educators all over the country, allowing me to improve my teaching and classroom. Aside from teaching, I am a wife, mother to 3 beautiful children, runner, hobby photographer and wannabe traveler! Ask me how to create an environment of self-assessment in your classroom!

Matt Rector – I’m Matt Rector.  I’ve been a teacher for 28 years.  I currently teach Integrated Mathematics 2 and 3 at Grant High School in Sacramento, California.  My current research targets increasing the effectiveness of mathematics instruction through a focus on literacy.
