The Maths Challenge. This term, we usher in a new teacher. His name is Kevin and he is from the UK. Within the time he spent with us, I participated in the mathematical challenge by his organization. It was interesting and I answered many difficult mathematical questions in the challenge. On my view, it is a successful activity. It helps us to learn the fantastic mathematical world and we can go up with each better because of this activity. I have learned a lot in the challenge. I learned how to deal with others better. I became a good leader in the challenge I think. Thank you Kevin!
