DAY 1: 25 May

Type a 100-word reflection for today's lesson.


After attending this online lesson, I found out that Coordinate Geometry was actually rather important in our daily lives. I also discovered that lesson on Distance and Mid-point was actually very much similar to finding an equation of a straight line using gradient and y-intercept. We can use two pairs of coordinates that are given to calculate the distance of two points and the coordinate of the mid-point. In Overall, I feel that I had benefited a lot from this enriching online lesson and this was indeed a fun experience. However, I had a little difficulty with the practice questions and that clearly shows that I would still need more practices.

DAY 2: 26 May


I personally feel that the lesson today was more challenging as compared to yesterday' one. This time, i took slightly longer to complete my task as there were many additional steps that we must take (for example: converting the equation into that of y= ). However, i must also agree that this lesson was also much more interesting. I applied the graph shifting method that i learnt in quadratic graphs and was finally able to complete my work. However, i feel that my knowledge on graph is still too shallow and i still need lots of practises. Overall, i feel that this online lesson was beneficial and enriching.
