Good morning here in Mexico and I think midnight in Australia Professor Woo: It gives me great pleasure to write from Tamaulipas, Mexico, I teach high school, working with students aged 15 to 18 years old. The class that my students and I share is differential calculus. I found you via a video on youtube ” the derivative, a visual approach ,” and I wonder , I found that after you mention that ” real learning real teaching ” and I agree with you. I downloaded some of their worksheets to work with my students. I will give credit to you, Professor Woo . Thank you very much for your input and I agree with you about how we share students and one professor of mathematics, so that students learn mathematics must present situations of context.

Best Regards
