Exploring Geometric Probabilities with Buffon’s Coin Problem
6th - 8th CCSS: Designed
New ReviewScholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.
Teaching Geometry Through Play
6th - 12th CCSS: Adaptable
New ReviewPuzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...
Graphs: Parallel lines
5 mins 8th - 10th CCSS: Adaptable
New ReviewParallel lines must always have the same slope. Learners use this bit of information to extend their equation writing skills. A video lesson explains how to write the equation of a line parallel to a given line and through a given point....
