My Currency Converter

Recently in math class we coded apps that could convert currency. We all made separate apps using the same slideshow made by Mrs Cleveland. The app can show you the exchange rate from Euros, Pesos, Pounds, US dollars, or Yuans to Canadian dollars. There is also a calculator that converts the amount of currency you typed in. We started by coding a dropdown box to choose the currency you wanted to convert and using an event block to show a set variable that contained the exchange rate. Then we used a different event block to calculate the amount of currency you typed into a text entry box. It was not always easy. Sometimes the slideshow was confusing or I would mistype some code without noticing it and it would make the app fail, but I did manage to complete it. I enjoyed seeing how combining certain blocks changed the way it worked, and experimenting with the code when it was not working as intended. I think everybody should learn at least a little about coding because of how prominent computers are in modern society. Here is the link to my app.

  1. Why no Yen? Also, can you make the link active? Anyways, this post is, of course, legendary, and is also snowy. (?)

  2. Wow! Great job Griffin! I saw that you went ahead. Was that challenging at times considering that it was harder to get help?

    • Mostly no, fortunately most of the time the slideshow was very detailed. Unfortunately sometimes it would be inaccurate or confusing and I would have to wait for help.

  3. Hey Griffin,
    I loved your post! Great detail and it’s very clear. One thing for next time would be maybe add some photos.

  4. Hi Griff! Great work! I love how invested you were in this project and the time and dedication you put toward making sure you found your mistakes and re-wrote the code for it to work. Yes, I also make mistakes and the slideshow will be altered for when I use it in the future. I would love to see a picture of your final app, and/or some of your code as a sample of what you did. Coding is going to be more prevalent in the future, do you think you may be interested in a career on the coding side of things? Your attention to detail and following steps was what made you succeed here, I have no doubt that now you are an official “coder” that you may dabble in it again in the future. What do you think? Well done!

  5. Hi Griffin,

    This sounds like a terrific math project. I loved reading your description of the steps you took to complete the project. Did you have to figure out all the exchange rates first in math class to make sure the right amount appeared on the currency converter? Did you ever get frustrated when you made a mistake? You actually learn more when you make mistakes. I loved that you persevered and completed the project. Would you like to make your own app one day? I bet you could make an amazing one.

    Keep on coding!

  6. A truly legendary post indeed!


    I echo all the other comments, and my only additional question for you is whether you think coding is a valuable skill that everyone should have some basic knowledge (like it should be part of Math or a separate course) or something that one could pursue if one had interest (like it should be an elective or club)?

    Keep up the legendary work!


  7. Depending on when you read this, the app link might have sent you to Audrey’s app instead, I don’t know why this happened but I fixed it.

  8. Dear Griffin,

    Great work! I really appreciated the explanation you gave on the different blocks you had to add to add conditional outcomes. I’m guessing the exchange rates are those that applied the day you inputted them into the program. I wonder if there’s a block of code that could pull real-time data and adjust accordingly?
    Did you learn any skills that could be applied to life outside of coding? You mention you might be interested in pursuing coding in the future, but even if you don’t, I would imagine there are still some valuable lessons to take from this.

    Thanks for sharing!
    Mrs. Thompson
