Bruce had homework regarding rotational symmetry and it totally confused me because I’m really bad at visual-spatial things.
What is rotational symmetry? That means a shape that can be rotated less than 360 degrees and still look the same. More info right here.
For spatially challenged people like me (you should see me parallel park!), rotational symmetry can be hard to picture. Hands-on learning can help.
A long time ago, I blogged about using flour and cookie cutters to learn about flips and turns. Guess what? That idea also works for rotational symmetry too!
A word to the wise: this activity is messy! It’s the perfect example of something that would be really hard to do with thirty fifth graders in a classroom, but doable with your child at home.
Just be sure to have a vacuum ready!
