Algebra | Whole Class
Students will review the meaning of variables and practice solving one-step and two-step linear equations. The lesson emphasizes showing each algebraic step clearly and checking solutions for accuracy.
| Term | Definition |
|---|---|
| variable | A symbol, usually a letter, that represents an unknown number. |
| constant | A fixed number in an expression or equation. |
| coefficient | The number multiplied by a variable. |
| inverse operation | An operation that undoes another operation, such as addition and subtraction or multiplication and division. |
| solution | The value of the variable that makes an equation true. |
Display two simple equations on the board and ask students to solve mentally or with quick work. Briefly review what makes an equation true.
Solve the warm-up problems, then share how they found the answers.
Model solving one-step and two-step linear equations step by step. Emphasize isolating the variable using inverse operations and checking the final answer.
Watch, take notes, and answer short guided questions.
Work through several equations with the class. Ask students to suggest the next step and explain why it works.
Solve problems along with the teacher, volunteering answers and reasoning.
Circulate, support students, and correct misconceptions as needed.
Complete a short set of practice equations independently, showing all steps.
Collect a brief exit ticket with one equation to solve and one solution-check question.
Independently solve the problem and submit their work.
Review the main steps for solving linear equations: isolate the variable, use inverse operations, and check the solution. Invite one or two students to summarize what they learned.
Formative assessment will be based on guided practice responses, independent practice accuracy, and the exit ticket.
Assign 6–8 linear equations for students to solve and check, including a mix of one-step and two-step problems.
