Title: Resolving Linear and Quadratic Equations

Grade: 3rd Year of Secondary School

Subject: Mathematics

Objective (PDA): To solve equations of the form Ax2+Bx+C=0 by factoring and using the quadratic formula.

Methodology: Inquiry-Based Learning

Interdisciplinary Approach: Incorporate problem-solving skills and critical thinking into the development of the lesson plan.

Session 1: Introduction to Linear Equations (50 minutes)

Phase 1: Introduction (10 minutes)

• Begin the class by discussing the importance of equations in real-life situations.


• Present the problem: "A car is traveling at a constant speed of 60 km/h. How long will it take to travel 300 km?"


• Ask students to write an equation to solve the problem.

Phase 2: Development (30 minutes)

• Introduce the concept of linear equations and their general form (Ax+B=C).


• Explain that a linear equation represents a straight line on a graph.


• Demonstrate how to solve linear equations using inverse operations.


• Provide examples of different linear equations and guide students in solving them.


• Discuss the concept of a solution and emphasize the importance of checking the answer.

Phase 3: Closure (10 minutes)

• Recap the main concepts covered in the class.


• Assign homework that includes solving linear equations.

Session 2: Introduction to Quadratic Equations (50 minutes)

Phase 1: Introduction (10 minutes)

• Recap the previous session by reviewing linear equations and their solutions.


• Present the problem: "A ball is thrown into the air. How long does it take for the ball to hit the ground?"


• Ask students to write an equation to solve the problem.

Phase 2: Development (30 minutes)

• Introduce the concept o
