Key Math Strategists – Who We Are

math strategy

We’ve been in your shoes. As former teachers, principals, and curriculum leaders with more than 100 years of instructional experience between us, we have witnessed several waves of educational reform pass through our states, districts, and classrooms–most recently the Common Core State Standards, which we firmly believe will help today’s students develop a meaningful, long-lasting understanding of mathematical concepts.

As your district implements the Common Core, we can help you make sense of the standards through a user-friendly professional development program, interweaving rich mathematics, technological tools, and our uncommon wisdom for classroom success. Jim Ryan began his career in education as a high school math teacher, working with at-risk students in the Academy program at Carlmont High School in the San Francisco Bay Area.

After five years in the classroom, he moved into administration. After 10 years in public schools, he joined Apple Computers to work on their PowerSchool software. At Key, Jim served as textbook product manager, professional development director, and director of marketing before taking on his current role as vice president of Key Math Strategists. Jim’s classroom experience continues to influence his work.

Whenever he evaluates an educational service or product, the first question he asks himself is, “How would this help my Academy students learn math?” Jim completed his undergraduate degree in mathematics at Cal Poly Pomona and his master’s in public administration at College of Notre Dame.

Tim Pope brings more than 10 years of teaching and administrative experience to his work at Key, as well as a passion for supporting teacher and student success. He taught mathematics at Hays High School in Kyle, Texas, and at the Liberal Arts and Science Academy (LBJ) High School in Austin, before becoming principal of St. Bonaventure High School, a 7-12 school on the Navajo Indian Reservation in Thoreau, New Mexico.

Prior to joining the professional development team at Key, Tim served as a program coordinator at the prestigious University of Texas at Austin’s Charles A. Dana Center, where he focused on facilitating systemic change with teachers and leaders through the Partnership for High Achievement and the AP Equity program.

At the Dana Center, Tim also led professional development workshops and coordinated the development of an online mathematics learning service. For the last six years, Tim has been working with school and district leadership to implement Key materials and to develop systemic professional development that improves teacher performance.Tim has a bachelor’s degree from the University of Michigan in Ann Arbor, a master’s degree from the University of Dayton in Ohio, and a certificate in private school leadership from the University of Dallas.

Karen Greenhaus has worked in education for over 20 years, the first 15 of those as a middle and high school math teacher, two as a district math specialist, and the last several as a professional development provider. Karen is excited about technology in education⎯for students and teachers⎯and is constantly brainstorming ways to incorporate technology effectively into mathematics to provide for a more dynamic learning experience.

At Key, Karen develops and coordinates professional development workshops, online courses, and webinars; she also trains and manages Key’s cadre of independent consultants and moderators. Karen earned a bachelor’s degree in mathematics from Virginia Tech and a masters in curriculum and instruction (with a math focus) from Virginia Commonwealth University. She is currently pursuing a doctorate in educational technology from the College of William and Mary.

Sandy Berger has worked with mathematics educators for more than three decades at the district, state, and national levels. She brings to her work a deep passion for equipping teachers with the tools they need to achieve classroom success. Her career in education began in Florida’s Leon and Gadsden counties, where she taught mathematics in low socioeconomic high schools for more than 20 years.

She also taught math education courses at Florida State University while working on her advanced degrees. For the past 15 years, Sandy has designed and delivered professional development for both American and international educators. Notably, she worked as a mathematics curriculum specialist at the Florida Department of Education and for the Southeast Regional Eisenhower Consortium.

She also served as managing editor of School Journals for the National Council of Teachers of Mathematics. Sandy earned a bachelor’s degree in Mathematics Education at Florida State University, a master’s degree in Mathematics Education at Florida A & M University, and a doctorate in Mathematics Education at Florida State University. She also has a certificate in gifted and talented education.

Drawing on his 9 years in the classroom and 6 years in educational technology, Scotty Thompson brings energy, passion, and fun to his work with teachers and students. Thompson supports the schools that adopt Key materials by conducting professional development sessions, assisting with implementation, and providing ongoing support. You can see his website, for graphing calculator reviews.

In addition to his work, Thompson is a regular speaker at mathematics conferences, where he covers such topics as complex instruction, cooperative learning, and using the Texas Instruments Graphing Calculator in the math classroom. Thompson earned a bachelor’s degree in economics from the University of California, Los Angeles, and a master’s degree in education from Stanford University.
