I’m Nicole Paul, an educator in the Madison Elementary School District with a passion for mathematics. I began my teaching career in 2010 as a 4th-grade teacher, where I quickly discovered my love for math education. After five years, I collaborated with a co-worker to departmentalize instruction, allowing me to focus solely on teaching math. This experience deepened my enthusiasm for the subject and helped me develop innovative strategies to support students in mastering complex concepts.After nine years in elementary school, I transitioned to teaching 7th-grade math at the middle school level, which challenged me to adapt to new standards and classroom management techniques. This role broadened my understanding of math education across grade levels and allowed me to support older students effectively.

Now, in my fourth year as a district math instructional coach, I work closely with teachers and administrators, providing professional development and sharing best practices in math instruction. As a member of the National Council of Teachers of Mathematics, I stay connected with a network of educators and continually access resources to bring the latest research and strategies to our district. My goal is to enhance our collective ability to meet the diverse needs of all our students across the state.
