Class Package

Class Project(s)
Students will make Javablocks projects including a variety of games and applications. These can range from simple to medium complexity.

Our Proprietary In-Browser Coding Platform.

The KTBYTE team developed the KTCoder™ with our students in mind! Most coding classes require software downloads, which is difficult and a hassle for young students. Our platform supports Processing, Javablocks™, HTML/CSS, and a bunch of libraries (like Soundcipher and Fisica!). This revolutionary all-in-one coding platform supports our interactive online classes, our specialized curriculum, and (most importantly) our student's passion for learning.
Live Student Help Hours with Teaching Assistants
Office hours are led by our highly qualified teaching assistants. It is an easy and free way to get immediate feedback on your code. Our homework is difficult - office hours can help you overcome obstacles and develop a stronger understanding of the material!
Student Progress Report
KTBYTE will e-mail parents with behavior and grade progess reports.

Class Description:

Fun2a teaches students computer science through block-based Java as they improve typing. After 6 months - 1 year of our course progression students will be coding at a high school level, and usually reach college level after 2-3 years. This course consists of 18 class sessions including a final project. Although students receive graded homework, most don't need to attend our office hours for homework help.


Fun1a / FUN1b, moderate experience in Scratch or similar environments, 5th grade math proficiency or permission of instructor.

Introduction to JavaBlocks

This is the introductory lesson for Fun 2. In this lesson we will be introducing the way Javablocks works. We will be creating a canvas, giving it a background color, and then modifying the color through the "Draw" function. We will also be adding shapes, images, and doing some basic motion.<br> <strong>Please complete the "In Class" Pset for MakeUp</strong>

Shapes and Variables

In this lesson, we will be reviewing how to draw shapes with different colors. Afterwards, we will introduce the idea of variables and how they can be used to create an art program.

Sprite Variables; Cookie Catcher

In this lesson, we will learn about Sprite variables, and will be making a simple catching game. We will have a "cookie" falling from the top of the page to the bottom. We will also have a "basket" at the bottom of the page which will catch the cookie and earn us points.

Treasure Hunter

In this lesson, we look at how we can use more advanced conditional statements to add more options to our programs. Specifically, we will create a treasure hunter game that uses a Sprite button and timer. Students will learn to build timers that either count up or count down and start on a button press.

Slideshow (With Functions)

A function is a way to compartmentalize and re-organize our code. We can create special blocks of code, name them, then "call" them in the main body of our program. In this class, we replace our normal "draw" function with several calls to other smaller functions which act as individual "draw" functions. In this way, we can draw different pages depending on what "slide" we're on.

Reaction Game

In this class, we will look at functions again, and use them to create a reaction time game! Students will have to utilize functions, frameCount, and random() functions to create a cheat-proof reaction time game. This program will borrow elements from the Stop Watch (CW 4) and Slideshow (CW 5) programs, so students may want to review those problem sets as additional homework.


In this class, we endeavor to build the classic game - PONG!

Pong pt.2, AI Opponent

In this lesson, we continue with our Pong project by finishing up the ball's behaviour, then adding an AI opponent to the game. Students will be surprised at how difficult it is to create an AI that is good enough to actually play the game, but not so perfect as remove any chance of beating it. It is easy to make a perfect AI, it is hard to program mistakes!


In this lesson, we will be creating a timing and accuracy based game modeled after the classic Fare Game: Whack-A-Mole.

Bebras Challenge Day

Today, we will be participating in the global computation challenge known as the "Bebras Challenge". Students will be tasked with solving computation problems at various skill levels. For every tier that a student completes, they will receive a certificate stating their completion of the challenge.

Sound Cipher Project

We are now able to implement sounds into our projects. Students will make use of the "Sound Cipher" blocks to create a mini piano and play some simple songs.


This week, we will introduce the students to the ArrayList, and how to add objects to it. We will create an ArrayList of sprites, then add a Sprite to it every time we click at our mouse's location. Time permitting, we can add effects like adjusting the size of the image we stamp with length of click or with key presses.

Maze Game

This week, we will be building a maze using sprites, arrays lists, and loops. The students will create an ArrayList of sprites called Walls, and we will check if the player Sprite is touching any of the walls. We will also include doors, moving objects, and goals!


Students choose web games to analyze and break down into their component parts.
