subhashree panigrahi replied to Colin McAllister's discussion When you are teaching or learning about symmetry, which examples do you use?"of course I use all of the above. besides that we consider examples from the class room itself and things possessed by children. for example, blackboard, books, different shaped pencil boxes, the window, the roof arc etc. "

Rashmi Kathuria replied to Colin McAllister's discussion When you are teaching or learning about symmetry, which examples do you use?"All of the above. Apart from this children are asked to create ink patterns using thread and observe symmetry. Paper folding activities are also taken up to learn and explore the concept."

What are the symmetry properties of a paper windmill?
If you take a square of stiff paper or thin card and cut and fold it to make a paper windmill, what does that teach us about symmetry? What if you begin with a regular hexagon instead of a square? You could post a photo of your construction to this forum, and explain how it works.See More

- Thank you sir, for being the first to accept me as a friend, secondly, the problem you just launched (i-e: the largest semicircle inscribed inside a square), I tried to give a solution but It does not seem to be of my level since I'm just a 9th grader but my enthusiasm for mathematics knows no levels! I'll be grateful to you for being with me in future!

hey sir, I saw your profile and amazed to know the great harmony I've found with you, I too want to become a software engineer in future and also my inspiration is Isaac Newton!!!
