Hi guys, sorry for the delay. Eventhough it is school holidays but I find that I am busier than how I used to be in my working days. Alright, coming back to the main aim of the blog, the sharing session. I have a problem in the topic sets, for me I find that this topic is easy to understand but my weaker students always get confused especially when they are required to shade the region involving union and intersection of sets. Can someone suggest to me, how I can teach better to help my weaker students.
