Craft instructions: Design rotationally symmetrical objects using basic materials: an eight-pointed star from two squares of cardboard and an eight-sided snowflake from paper by folding the paper and cutting out shapes.
This craft makes it possible for the students to tangibly experience the important characteristic of “center of rotation" as a rotating connection of two cardboard disks.
In the case of the snowflake, the “center of rotation" is the point of intersection of all fold lines in the paper.
