Write and Solve Addition Equations Using a Bar Model

This Write and Solve Addition Equations Using a Bar Model video also includes:

Solving equations is a crucial part of algebra. This video shows how to set up those equations using the bar model. This method is a visual way to understand which parts make up the whole and solve for the missing piece. The problem is eventually solved using inverse operations and reviews necessary steps. Video is first in a series of four. Other videos practice subtraction, multiplication, and division with bar model.
