Even though she always loved math, Emily failed to grasp a conceptual understanding of many of the topics she was learning. As she began to teach math, she became passionate about helping students understand the "why's" behind the math.
Developing mathematical understanding is very much tied together with problem solving skills. When students ask Emily "When are we ever going to use this?", she reminds them that even if they never need this particular math skill in "real life", the reasoning and problem solving skills they are learning and utilizing will be crucial in whatever they go on to pursue in the future.
