**Big Ideas**:

- Apply properties of operations to add, subtract, factor, and expand linear expressions with rational coefficients
- Understand that expressions can be written in different forms to shed light on the problem
- Solve real-life mathematical problems with positive and negative rational numbers
- Assess the reasonableness of an answer using mental computation and estimation strategies
- Use variables to represent quantities in real-world or mathematical problems and construct simple equations and inequalities to solve problems
