These two multi-day class projects with teacher guides, student worksheets, and solutions projects introduce students to Pascal's triangle using methods besides numeric patterns.
The project "Pascal's Triangle through Plinko" can stand alone or lead in to the second project. Students toss coins to simulate a ball falling through a Plinko board, and then use an applet [Quincunx] to simulate a much larger number of trials.
"Pascal's Triangle though Paths" begins with students walking out lattice paths to various points on a grid made of tape on the floor. On the second day, students extend their results, look for patterns, verify Pascal's Identity using lattice paths, and consider extensions as time allows. This project also can stand alone or follow the first project.
