Introduction
Have you ever wondered how math helps solve real-life problems like budgeting, shopping, or saving money? In this WebQuest, you will explore how linear equations can be used in everyday situations. Get ready to become a problem-solver and discover how math works in real life!
Task
Your task is to:
- Solve real-life problems involving linear equations
- Work with your group to create a short presentation or poster showing your solutions
- Explain how you arrived at your answers
Output:
A poster or PowerPoint presentation showing:
- At least 2 real-life problems
- Solutions using linear equations
- Explanation of steps taken to get the answer
Process
Follow these steps carefully to complete your activity:
1. Review the concept:
First, read and study what linear equations are, their characteristics, and how they are formed.
2. Gather information:
Use the resources provided below to watch videos and read materials that explain how to write and solve linear equations.
3. Analyze problems:
As a group, discuss and solve the given or chosen real-life problems. Make sure to show each step of your solution clearly.
4. Create your output:
Organize your work into a poster or slideshow. Arrange your problems, solutions, and explanations in a way that is easy to read and understand.
5. Present your work:
Share your group’s output and findings with the class. Be ready to answer questions about your solutions.

Subject/Topic: Mathematics – Linear Equations and Real-Life Applications
Target Learners: Grade 8 Students
Time Required: 1 to 2 class periods (approximately 40–60 minutes each)
Learning Objectives: By the end of this activity, students will be able to:
1. Define and identify linear equations correctly.
2. Translate real-life situations into mathematical statements or linear equations.
3. Solve linear equations accurately and explain the steps used.
4. Work collaboratively with group members to complete tasks and present results.
5. Recognize the importance of mathematics in solving everyday problems.
Prerequisite Skills:
Students should already have basic knowledge of algebraic expressions, operations with integers, and simple equation-solving techniques.
Preparation:
- Prepare grouping arrangements for students.
- Ensure students have access to devices and internet connection to view the resources.
- Prepare materials needed for creating outputs (cartolina, markers, art materials, or presentation software).
Implementation Guide:
1. Introduction (5–10 mins): Discuss the importance of math in daily life and introduce the topic and activity.
2. Information Gathering (15–20 mins): Allow students to explore the given resources to review and learn concepts.
3. Collaboration and Creation (20–30 mins): Guide groups as they discuss problems, solve them, and create their outputs. Provide assistance when needed.
4. Presentation and Discussion (20–30 mins): Let groups present their work. Provide feedback and clarify misconceptions.
5. Evaluation: Assess student work using the rubric provided.
Adaptation:
- For advanced learners: Provide more complex real-life problems involving two variables or multi-step equations.
- For struggling learners: Provide guided worksheets, simplified problems, and additional examples to help them understand the concepts.
