Direct, Inverse and Joint Variation

Had to cover this topic during the exam week coz it will also be included in the midyear exam. Thankfully there was a break in the Form 5 exam schedule. Discuss the problems from PATS 5 with my girls. This is another topic that is very easy and can be covered in 1 or 2 periods only. The girls were able to solve the problems given. Its a happy moment for me to see the happy faces of my students when they're are able solve a problem. As I mention earlier, the 5 KA girls are my 'special' girls. I've seen a lot of changes in them. You see I've been teaching them since Form 4. This year they are more eager and serious to learn except one or two students. I really have to work more closely with this 'one' particular girl. It's quite difficult to give full attention to her coz I have one whole class depending on me (as oppose to my 4 SA class as majority of them are able to do maths with just a little bit of help). The extra class I have with a few of the 5KA students seem to be helping them cope with math. Maybe I have to schedule personal tuition for this girl after school. I'm always willing to help out coz I'm usually available after school (except when I have to go for courses or meetings).

I'm putting up this video on direct, inverse and joint variations for your revision
