TEACHING EXPERIENCE

Taught grades 3–6 all subjects. Taught 7–8 math. Instructional Computing Consultant, Assessment and Technology Coordinator, K–8 Principal, Elementary Math Methods Lecturer.

MY TEACHING STYLE

Interactive, questioning, respectful, humorous, supportive, innovative, flexible approach to teaching and learning. I utilize manipulatives, models, and strategies to teach math meaningfully to pre-service teachers. I advocate for better ways of making math understandable and enjoyable. The Singapore Bar Model is my favorite pre-algebraic model for problem solving.

ADDITIONAL BIOGRAPHICAL INFORMATION

This is my 44th year as an educator and I'm still excited to be involved in the best profession available! Thirty-six years ago, I left education for double the pay—discovered that money wasn't really what motivated me and have been elated to be an educator ever since. I had left a job where I liked everything except the pay to take a job where I liked nothing except the pay. Thrilled to have learned the lesson so early in my career.
