Required Materials

A collection of objects that are a circle or have a circular face. Examples include plates, cans, cookie tins, and hockey pucks. 


Coins

Colored pencils

Graphing technology

Examples of graphing technology are: a handheld graphing calculator, a computer with a graphing calculator application installed, and an internet-enabled device with access to a site like desmos.com/calculator or geogebra.org/graphing. For students using the digital materials, a separate graphing calculator tool isn't necessary; interactive applets are embedded throughout, and a graphing calculator tool is accessible on the student digital toolkit page.
