Code to Create: Solving Real-World Problems with Algorithms

Introduction

In today’s digital world, computer science is not just about writing code but about solving real-world problems using logical thinking, algorithms, and creativity. In this WebQuest, you will explore how coding concepts such as algorithms, conditionals, and variables are used to design solutions to everyday problems.

Guiding Questions:

  • How do algorithms help computers solve problems?

  • How can conditional statements improve the efficiency of a program?

  • How can coding be used to solve real-world problems?

Learning Objectives:

By the end of this WebQuest, students will be able to:

  • Explain how algorithms are developed to solve problems (Understand)

  • Apply conditionals and variables to create a basic program (Apply)

  • Analyze how code decisions impact program outcomes (Analyze)

  • Create and present a coded solution to a real-world problem (Create)

Florida B.E.S.T. Standards Alignment (Computer Science):

  • SC.BE.1.1: Use algorithms to solve computational problems

  • SC.BE.1.3: Design programs that use variables and conditionals

  • SC.BE.1.4: Explain how computing solutions impact society

Bloom’s Taxonomy Levels: Understand, Apply, Analyze, Create

Task

You will work in a small group to design a narrated Google Slides or PowerPoint presentation that explains a simple coding solution to a real-world problem. Your presentation must include:

  • An explanation of the problem

  • A step-by-step algorithm

  • Sample code using variables and conditionals

  • A brief explanation of how your code works

  • A narration explaining each part of your solution

At the end, your group will present your project to the class.

Process

Step 1: Form Groups

You will work in groups of 3–4 students.

Step 2: Assign Roles

Each group member must have a clear responsibility:

  • Project Manager: Keeps the group organized and on task

  • Coder: Writes and explains the sample code

  • Researcher: Finds examples and explanations of coding concepts

  • Presenter/Designer: Creates slides and narrates the presentation

Step 3: Choose a Problem

Select a real-world problem that can be solved using code, such as:

  • Deciding what to wear based on weather

  • Calculating grades

  • Determining ticket prices based on age

  • Managing a simple to-do list

Step 4: Research Coding Concepts

Use the following resources:

Step 5: Create Your Algorithm and Code

  • Write your algorithm in plain language

  • Convert it into simple pseudocode or actual code

  • Use at least one variable and one conditional statement

Step 6: Build the Presentation

  • Create 6–8 slides

  • Add narration explaining each slide

  • Include visuals, diagrams, or screenshots of code
