Fractional parts of a circle
thingiverse
These are fractional parts of a circle I use for my 6th grade to teach them a basic understanding of how summation works. Included fractions are: * <sup>1</sup>⁄<sub>2</sub> * <sup>1</sup>⁄<sub>3</sub> * <sup>1</sup>⁄<sub>4</sub> * <sup>1</sup>⁄<sub>5</sub> * <sup>3</sup>⁄<sub>4</sub> * <sup>2</sup>⁄<sub>3</sub> I printed every fraction a few times each in their own color so they can lay them beside each other to form a full circle. The first task is to assign each part the right fraction. Then they have to lay multiple different parts together to form nearly a full circle. They see that a tiny part to 1 is missing and calculate the exact fraction of the sum. See the (german) worksheet for more information.
