Rotational Symmetry
January 28th, 2008 · 3 Comments
Demonstrate the use of tracing paper in checking the rotational symmetry of a shape. Using “virtual” tracing paper you can demonstrate this method using an interactive whiteboard. Place a shape. Place the tracing paper then draw on to it using the interactive whiteboard. Use the rotate tab to count the order of rotational symmetry.

Hi, yet again,so impressed. I have not found any great resources to really show rot. symmetry well and this does. We played a game where the kids had to colour round the shape and everytime they went wonky, the other team got a mark. They loved it! Then real bonus points for the correct order of rotation. Thanks so much. Got a bit fed up this week as lots of my free resources are now not free and you still are..hope it stays that way because myself and my kids could not do without your brilliant resources. Kind regards patricia

Hello again. I’m glad you liked it as this resource isn’t used very much – I was starting to wonder if there was a fault with it that I couldn’t find. Thanks for sharing how you used it. That might help others.
As for staying free it will remain that way permanently.
Thanks again for the feedback, Spencer

One hour after finding a factor resource for my lesson I am still amazed at all these brilliant resources. I hope to use several of them.
