What I did was cut out different shapes out of card stock. (If you have a die cut machine I would use that because cutting them individually was quite the task) N-E-WAYS....so I attached it to a piece of poster board using a simple brad so that the shape can be rotated. (The poster board is one giant piece cut into four smaller pieces)
The students will rotate the shape 90 degrees, 180 degrees, and 270 degrees drawing the shape each time to find out if it has rotational symmetry. Also, if it does then at what degree. I drew the star and the lines for the kids to match up and remember where the shape started.
See this one does not have rotational symmetry.
But this one does!!! It looks the same but if you look for the star they have to line up it is upside down. You could make yours much prettier with fancy paper and colors!!!
Well I hope you all enjoyed my newest lesson plan idea, and I hope my absence does not mean that you are no longer my readers. Talk to you all next time!
