Subject: What persentage of something makes something?
Hi! I have been preparing myself for an interview to be able to enter PGCE secondary maths teaching course. I suppose to choose an age group and a level together with a topic to make a five minutes individual presentation. I decided to teach percentage (actually it suppose to be only introduction part of a lesson) to year 9 and level between 5-7. I have been reading as much as I can to see the reality of teaching in every aspect. I found this site by chance and read first couple of messages about teaching percentages. Thanks to every one whose shared their experiences. I have got some idea when I was reading yours and would like share it with you. I hope it will help you to make your job easier. WHAT PERCENTAGE OF SOMETHING MAKES SOMETHING? Example: What % of 11 is 55? X= 100 < of < < < 11 > > > > > >55 is In here; 'WHAT' means 'X', 'percent' means '100', 'of' means 'multiply', 'is' means 'divide'. Now we can put this simple instuction into calculation form. X = (100 x 11) / 55 = 1100 / 55 = 20 Always follow the same directions to set the numbers and unknowns in the same place before you construct the calculation form. Do you think it will help you to teach percentages easier? I hope so. If so, wish me luck please. My interview on 5th December 2006!
