Dear All How would you teach Pythagoras to a Year 7 class and Year 9 support class? I know that prior knowledge required is squared numbers/squared roots/ areas of squares/recognising right-angled triangles. Also does anyone have any resources for these? I am not a teacher yet but i may need to do a presentation on any one of Yr7, Yr9 top, Yr support, Yr 11 top and Yr middle sets and a year 13 class.( i am a MEC student) I understand that for a Year 7 class you would need to explain all the prior knowledge first and maybe a bit of a background on Pythagoras. But how would you teach it to a Yr 13, when you'd expect them to already know this. Also if any of you have taught Pythagoras to a Yr 7 class, which parts do they find diffcult to grasp? If anyone could shed some light into this, that would be good. Thank you.
