DAY 1: 25 May

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

Reflections
I felt that todays e-learning was quite challenging but fun. It was fun to find the mid points as you would know the exact middle of a line. However, it is also challenging as you have to apply Pythagoras Theorem, etc. Playing with negative numbers was also fun, as you need to subtract and remember to take away negative sign when finding length. All in all, today's lesson was enriching.

DAY 2: 26 May


Type a 100-word reflection for today's lesson and comment on your work.
Reflections
I felt that today's e-learning was even more challenging than yesterday. However, it is very enjoyable as we can now draw circles with the GC. I think that my work is not perfect as the Graphing calculator's circles are not 100% correct, as you can see, there are some holes in between. However, I think that I have done my best to solve the problem. All in all, today's e-learning was very fun. However, I am unable to finish some parts of the designs because I do not know the exact positions as every time I try, the digram would be a bit off.
