The document outlines lessons 8 and 9 of module 7.2, which focus on applying properties of operations to add and subtract rational numbers. It provides learning objectives, homework assignments, and examples for students to work through. These include representing a situation involving weight change with rational numbers and using properties to simplify expressions. The lessons aim to teach how properties can help when finding sums and differences of rational numbers, and whether they could also aid with multiplication and division.
