Grade 6. This describes the skill, not a learner estimate.
Dependent and independent variables
Connect two related quantities in equations tables and graphs
Problem types
- Equation for a quantity at a steady rate
- Name the independent and dependent quantity
- Write the equation from a table and graph
- Use an equation between two variables
- Complete the equation of a table
Builds on
- Expressions with variables
- Graphing in the first quadrant
- Patterns in the operations · Useful idea
A table pairing a situation's two quantities shows how the output depends on the input, which an equation then writes down.
Leads to
- Representing a proportional relationship
- What makes a relation a function
- Linear equations from constraints · Extend the idea
Naming the independent and dependent variable sets up a linear equation whose slope and intercept have meaning in the situation.
- Naming the quantities in a model · Extend the idea
Naming the independent and dependent variable begins modeling, and each modeled quantity also needs a unit.
