Profile

I love math! I realize that many of you may not share that thought. That is ok. I hope that through this course you are able to master the appropriate materials to move on in your pursuit of teaching as well as realize that math is the key to opening many opportunities for you. Learning math and feeling confident will enable you to pursue any endeavor you desire. I firmly believe that making a class engaging and fun helps students learn the material. I feel that students learn better with their peers. Group works utilized heavily in my courses. I look forward to helping you succeed in this course and your future.
