In this lesson, you learned how to:

• Use words and equations to describe the patterns in a table of values or in a set of calculations.
• Use representations, like diagrams and tables, to help make sense of a described situation and write equations for it.

Here are the activities that helped you reach those goals:

• 1.3.1: Finding a Relationship between $x$ and $y$
  • In this activity, you brainstormed ways to find the relationship between variables in a table.
• 1.3.2: Describing Relationships Using Words and Equations
  • In this activity, you matched tables with the equations that could model the relationships in each table.
  • 1.3.2: Self Check
  • 1.3.2: Additional Resources
• 1.3.3: Identifying and Representing Relationships
  • In this activity, you created tables from a situation and then wrote an equation to model the relationship.
  • 1.3.3: Self Check
  • 1.3.3: Additional Resources
• 1.3.4: Writing an Equation to Represent a Relationship
  • In this activity, you wrote an equation to model a relationship in a situation and also began to solve an equation given one of the quantities in the equation.

After these activities, you completed the following practice :

• 1.3.5: Practice
