Symmetry - Rotational


Rotational symmetry is when an object can be rotation on a central point and look the same. For this project we cut a sheet of white paper into a square and folded it corner to corner 3 times (like you would fold to cut out a paper snow flake). On the top triangle the children can draw their starting pattern. We drew our names or simple designs.

Then, unfold one fold and use a window or light board (we used our glass front refrigerator!) and trace your design on the blank triangle. Repeat this - unfold and flip/turn the paper as needed - to trace the design on all 8 creased triangle areas.




 Then open all the folds to reveal the rotational symmetrical design!





For some added fun, we decided to add color to our designs. Remember it has to be symmetrical so the colors should match in each triangle section too!
