Balance Point Calculations

Attached are some of the assignments we use to for our Geometry students to practice applying ratios by calculating the balance point for balanced systems. Also attached; an activity homework sheet for when we take turns to try to balance on a board on different sized round cylinders and a triangular prism, and a copy of the instruction sheet we hand out.  For the activity we use a board about 18 inches long, a round cylindrical tube about 3.5 inches outside diameter, a round cylindrical wood dowel about one inch diameter and a short piece of 1-1/2" angle iron.
