Algebra 11.1.6 Lesson Summary

Search for key terms or text.

In this lesson, you learned how to:

  • Tell which quantities in a situation can vary and which ones cannot.
  • Explain the meaning of the term “constraint.”
  • Use letters and numbers to write expressions representing the quantities in a situation.

Here are the activities that helped you reach those goals:

  • 1.1.1: Understanding Value 
    • In this activity, you wrote equations to solve problems about a meal. The big thing you learned is that an equation is a statement that an expression has the same value as another expression. An equation can have letters, numbers, or a mix of letters and numbers.
  • 1.1.2: Creating Expressions to Estimate Cost, Part 1
    • In this activity, you learned how expressions could represent the quantities in a situation like planning a pizza party. You also saw how expressions could change if quantities changed.
    • 1.1.2: Self Check
    • 1.1.2: Additional Resources
  • 1.1.3: Understanding Constraints
    • In this activity, you continued working with the pizza party and learned that a constraint is something that limits what is possible or reasonable in a situation.
    • 1.1.3: Self Check
    • 1.1.3: Additional Resources
  • 1.1.4: Creating Expressions to Estimate Cost, Part 2
    • In this activity, you wrote expressions and examined constraints for the cost of an ice cream party for the ninth-grade class.

After these activities, you completed the following practice:

  • 1.1.5: Practice
