The class learnt about circumferences but was confused about area of circle.
I had to re-teach the portion on the homework assigned in the textbook, P6B, Pg17, Qn (f)
Later, a few students still did not divide by 2 or multiply by half to find the circumference of semi-circle.
A few were confused and MINUSed when finding the perimeter of a figure which had a smaller semicircle within a larger semicircle. I think they were thinking of finding the area.
A few of them realised their mistake when I highlighted it to them during Com Lab time.
I think they need a few more exercises on calculating the circumference of circles in figures.
