Am mboya Charles a teacher of mathematics and geography. am a qualified teacher registered by teachers service commission in my country. I have bachelor's degree in education specializing in mathematics and geography. in teaching mathematics i use simple charts and ensure that the teaching is all about learner centered as well as using simple formulae that can be easily memorized and mastered by the students and in teaching geography i use charts of drawings representing physical geography this will help learners memorize the concepts since what is seen sticks into my mind as compared to what is learnt theoretically.
