Lucas is a mathematics teacher for about 7 years now. Currently, he is working in the Navajo Nation area in New Mexico and it has been a great teaching experience for him since he has students in various learning level. He enjoys working with students in solving mathematics problems for the reason that, while he is teaching them, he also learns from them. This experience of teaching here opens his horizon of how really educational setting and upbringing differs from one culture to another. And this made him realize that teaching really is one of the careers and vocation that will expose us in a huge ideal of life learning.
