Lesson Narrative
Students begin the lesson by analyzing the role variables play in equations. They then dig into what it means for an equation to be true or not true. Since grade 1, students have been identifying whether numerical equations are true or false. Now, students extend that understanding to algebraic equations. Students learn that, for an equation with a variable, a value of the variable that makes the equation true is called a “solution” of the equation. They then use substitution to determine whether a given number in a set is a solution of the equation.
This lesson is where "next to" notation is introduced for multiplication. (For example, means .)
- Comprehend the word “variable” to refer to a letter standing in for a number and recognize that a coefficient next to a variable indicates multiplication (in spoken and written language).
- Generate values that make an equation true or false and justify (orally and in writing) whether they are “solutions” to the equation.
- Use substitution to determine whether a given number makes an equation true.
Let's see what it means to find a solution for an equation with a variable.
