Term 2 Week 3 - 4T1 Mathematics - Arc Length and Area of Sector

Did Arc Length on Monday and Area of Sector on Wednesday. Class were always ready for lesson and on task except for some disruptive boys (just being playful). Quite difficult to bring across the concept of proportion to get the formula for Arc Length and Area of Sector. What the students did were just to memorise the formula. I believe for NT class, this may be sufficient as long as they can do the questions. One major mistake is not having the habit of writing down the units (square cm or degree). Generally the class is gearing up to prepare for their N level exam this year.
