Message to Students
and/or Parents:
Doing Math Problems is an enjoyable experience. I always insist students to do the math problems on their own initially. No matter whether it is right or wrong. Because this makes the student think on their own. I will always be there to improve their solutions and explain according to their level of thinking.
