Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
Learning Targets (I can)
Describe an equation.
Describe an inequality.
Select values to make an equation true using substitution.
Select values to make an inequality true using substitution.
About the Math
Describe an equation.
In elementary grades, students explored the concept of equality. In 6th grade, students explore equations as expressions being set equal to a specific value.
Describe an inequality.
Inequalities state the comparison of two expressions.
Select values to make an equation true using substitution.
Select values to make an inequality true using substitution.
The solution is the value of the variable that will make the equation or inequality true. Students use various processes to identify the value(s) that when substituted for the variable will make the equation true.
Essential vocabulary for this standard includes: inequalities, equations, greater than, >, less than, <, greater than or equal to, ≥, less than or equal to, and ≤.

If x = 5, then 2x + 4 = 14. Explain why this is true.
What value of n makes the equation 4n + 6 = 30. Explain how you solved this.
Tony said the value of c is 7 and Jayla said the value of c is 6 in the equation 4 + 4c - 5 = 23. Who is correct? How do you know?
How can the equation f + f + f - 6 = 3 help you solve the equation 3f - 6 = 3? Explain.
SLIDE-BASED TASKS
These links are HCPSS created instructional tasks. These tasks are provided in Google slides.These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first(often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
These publications have been provided for each school. They are typically stored in team closets or the media center. Check with your team leader if you cannot find them.
