Algebra Session 6: Solving Equations

In the previous session, we looked at linearity in different situations. We used spreadsheets to work with linear functions in tables, equations, and graphs. We also explored connections between rates and slopes, and examined the role of independent and dependent variables in linear functions. Now that we have explored characteristics of equations for lines, we will develop strategies for solving linear equations in this session.
Note 1

Part A:
Equality and Balance

Part B:
False Position and Backtracking

Part C:
Bags, Blocks, and Balance

Homework

In this session we will explore different methods for solving equations. We will:
•	Learn more about the meaning of the equal sign
•	Explore the connection between equality and balance
•	Solve equations by balancing, working backwards, and inverting operations
•	Explore the strengths and limitations of different models for solving equations
•	Solve systems of equations


	Throughout the session you will be prompted to view short video segments. In addition to these excerpts, you may choose to watch the full-length video of this session.
