I have been teaching Maths, English and Science to students of grade 5 till 8.

Math teaching is best done with an emphasis on real-world problem-solving and conceptual understanding, which aligns with your experience in business process analysis and stock trading. ​Teaching English to adults, especially professionals, should focus on practical communication skills (Communicative Language Teaching) and building fluency. This aligns perfectly with your soft skills training background (communication, negotiation). Science teaching, like business training, benefits from an inquiry-based, hands-on approach that uses data and real-world phenomena.
