Get started at

Welcome to CoderDojoKC! Let’s get you started!

Looking for something to do? Practice your typing skills! is a great way to keep your fingers nimble and learn where some of those tricky keys are located.

Are you working on the debugging challenge? Remix it here!

Step One: Wifi

1. Open up your internet connection and connect to “Fiber Public WiFi

2. Can’t connect? See if you can get to the wifi sign-in at

3. Still can’t connect? Raise your hand and a mentor will get you a hotspot to connect to.

4. We recommend using the Google Chrome browser.

Step Two: Start Learning!

If you don’t know which programming language to start learning, we recommend Scratch (if Scratch is not to your speed, check out the link in the sidebar on the right).

You will need a parent or guardian’s help to create a Scratch login:

  1. Click “Join Scratch” in the upper right-hand corner of the Scratch site.
  2. Create a username that does not include your real name.
  3. Think of a password that you can remember easily. You should have your parent or guardian write this down and save it.
  4. Click “Next” and continue following the directions. You will need a valid email address (yours or your guardian’s) to continue.

Once you have a Scratch login, use the links below to build something awesome.

Step Three: Learn to Code

1. Are you brand new to coding? Start with Codecademy (recommended for 13 years & up) or Scratch (recommended for 12 years & under).  Want to try building your own phone application? Check out App Inventor! Be sure to create an account and write down your username and password so you won’t forget!

2. Do you have a little coding under your belt? Are you ready to learn more? Check out these fun games:

3. Were you working on a project from our last session? Feel free to continue on that, and ask mentors if you need any help!

4. Get started on the new project. We can’t wait to see what you create!

Today’s theme: Teach us something

Today’s Concept: Multiple Choice & User Input

If you ask almost any developer-mentor in this room who they write programs for, they will all tell you that they write them for clients, other people. All of these programs rely upon input from those other people in order to be useful. If you think about the games that you love to play, those games are fun to play because they rely upon some kind of input from you — it could be the press of a button, wiggling a joystick, or typing an answer. Today, we’ll look at the a user selecting an option in order to provide input for your program.

In Scratch, we have one way of getting user input as a selection, in the form of a button: . This will fire an event that you can act upon.

In JavaScript, you can get user input by using a form. A form can take in text, ask questions where the user has to select either “yes” or “no,” offer a dropdown list for users to select one or more options, and others. Each form part should have a unique ID since that the answer to that part of the form will be tied to the ID.

<input type="radio" id="firstGroup" value="2013"> October 5, 2013 </input>
<button type="submit" id="submit">Submit</button>

In JavaScript, you would then pull information out of that form to be used in your code. You can do that by assigning the data tied to those form group IDs to variables.

var answer = document.querySelector("#firstGroup");

You can then check the answer by using an if-statement.

if (answer == "2013") {

The Mozilla Developer Network has a great introduction to forms if you’d like to learn more about creating forms in HTML.

For today’s session, we want to see at least two things in order to be eligible for presenting to the group: The theme of teaching us something and the use of a button selector.

Step Five: Show Off!

Did you create something awesome based off of one of these projects? Come present it on stage! Presentations will start at 11:30 am. Let a mentor know you want to show off your work. Scratch projects that will be presented will be added the CoderDojoKC Studio by a mentor.

**Presentations may not contain any politics, violence, gore, or bad words. (And we’re counting “sucks” as a bad word!)
