ACT
In this task, students investigate how many coins will fit around a central coin when they are all of the same denomination, and if there is room left over. The teacher is given a chart of four coin denominations and their diameters, but students are encouraged instead to measure the coins themselves. Solutions through experimentation and through the application of trigonometry are provided. Aligns with G-SRT.C.8 and G-MG.A.
