Scale / Balance Math Problems - video lesson

A balance gives us a simple model for equations in beginning algebra. In this lesson for 4th or 5th grade, I solve 14 different balance problems, starting from the most simple and advancing to some that have double scales. Students learn the principles of dividing both sides of the equation by the same number and removing (subtracting) the same amount of both sides of the equation.
