Students use bar models to solve one-step addition equations. They analyze a Worked Example and finish partially completed examples using the bar model. In each equation, students decompose the bar for the addition expression into two parts: one part representing the variable, and one part representing the constant. Day 2

Overview of lesson
The document introduces bar models as a visual tool to represent and solve one-step addition equations, where bars are used to depict quantities and breaking the bars into parts shows the relationships between values; worked examples demonstrate using bar models to reason through equations and determine solutions as well as an alternative ...
We are interested in finding a particular solution to this initial-boundary value problem. In fact, we can represent the solution to the general nonhomogeneous heat equation as the sum of two solutions that solve different problems. First, we let \(v(x, t)\) satisfy the homogeneous problem
