Maria Miller grew up in Finland and earned a master's degree in mathematics there in 1997. She enjoys both math and teaching, so becoming a math teacher was an easy choice. Miller began creating math books in 2002 as a result of her tutoring experiences with homeschooling youngsters. She believed the books they were using were inadequate, particularly in terms of conceptual knowledge of mathematics, so she began writing books that focused on the concepts and why of mathematics, while also emphasizing the how and the importance of practice. Her resources have grown in popularity and esteem among parents and instructors over time. She enjoys walking, bicycling, swimming, reading, assisting with Inspire4.com, playing the piano, and listening to music in her spare time.
