School Improvement in Maryland

Lesson Plan: Lesson plans were written by Maryland mathematics educators and could be used when teaching the concepts.

Goal 1 Functions and Algebra

Expectation 1.2 The student will model and interpret real-world situations using the language of mathematics and appropriate technology.

Indicator 1.2.1 The student will determine the equation for a line, solve linear equations, and/or describe the solutions using numbers, symbols, and/or graphs.

Lesson Content

Systems of Linear Equations - Standard Form

Objectives

  • Students will write systems of equations and find solutions to systems of equations.
  • Students will explain how they determined their solutions to a system of equations. Students will also justify their solutions.
  • Students will write equations in standard form and then graph the equations using slope-intercept form.

Other Indicators Addressed

1.2.3 The student will solve and describe using numbers, symbols, and/or graphs if and where two straight lines intersect.

Materials Needed
