• Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of conjectures by mathematical proof. When mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.

    My name is Mandy Olson and I am excited about my sixteenth year teaching mathematics.  I teach a variety of math courses and enjoy the connections they all make with each other as well as how knowledge builds from one course to another.  This year I will be teaching Basic Math, Statistics, Finance, Pre-Calculus, and College in the Schools Calculus.  In my spare time you can find me with my three daughters.  We keep very busy with sporting events, beach trips, hiking/biking adventures.

    I graduated from the University of Wisconsin – Stevens Point with a degree in Mathematics Education. AFSA offers a lot of methods and resources to create learning environments that are memorable and enjoyable. I am excited to incorporate these resources this year to make math enjoyable. Additionally, I am thrilled to observe each student grow, as a mathematician and as a human. I believe that with your hard work, or your student’s hard work, each and every student will be able to succeed. During my free time I enjoy spending time outdoors, grilling, and watching my favorite Chicago sports teams.

    Hello! I am Rasha Mae, and this is my second year as a math teacher at AFSA! I have a 5-12 Math Education degree from Bethel University and an in-progress Master’s degree in Special Education. It is my sincere belief that learning begins in an environment where each student is known, valued, safe, and respected. With this foundation and AFSA’s authentic experiential curriculum, I look forward to fostering students' growth as learners and as people through curiosity, critical thinking, creativity, and collaboration. Other than teaching, I enjoy meditating in nature, playing piano, cooking new recipes, and spending time with my friends and family.

    Hello, my name is Mr. Walstrom! I am excited to be working with you or your student this school year and diving into how math and programming is used in the real world. Here is a little bit about me. I received my bachelors of science degree at the University of Wisconsin River Falls with a major in secondary mathematics education and a minor in computer science and I am currently pursing my masters degree in software engineering. Some of my hobbies include: playing guitar, weightlifting, woodworking, and playing video games. I also am a very avid Minnesota Vikings and Star Wars fan! I am looking forward to meeting you or your student this school year!
