How to Teach Students to Build a Bill Calculator in a Web Development Course?

Hey everyone,

I’m working on a web development course and want to include a project where students can create tools like a bill calculator. I found an example of one online, and it got me thinking about how to teach the logic behind such projects, especially how to handle inputs like units or changing rates.

I’m finding it a bit tricky to break down the backend logic in a way that’s simple enough for beginners. Has anyone taught something similar before? Any tips on how to keep the project interactive and easy to understand for students who are just starting out with coding?

Would love to hear your thoughts!

Hi, we usually break down the logic based on the features. Specially features that require different algorithms. You can start by tasking them to build the basic server that serves a hello world endpoint. Then you can task them the features one by one or even multiple ones together if you find them easy to implement. For each task you can include some hints and maybe a bunch of comments in the initial boilerplate showcasing the steps they need to take in order to finish the feature.

To effectively teach students the logic behind building a bill calculator, break down the process into smaller steps. Start with fundamental concepts like variables, data types, and operators. Guide them through input handling, validation, calculations (subtotal, tax, total), and output display. Incorporate NJ DMV interactive elements like unit selection and dynamic rate updates. Use visual aids, debugging exercises, and real-time feedback to enhance the learning experience. By focusing on a step-by-step approach and providing clear instructions, you can help students grasp the underlying logic and build a functional bill calculator.
