natan-js - Maths Game for Kids

A web based app I made for my nephew. Intended to teach young kids basic arithmetic (addition and subtraction) with positive numbers.

Features

• Addition ➕
• Subtraction ➖
• No negative numbers
• Input using touchscreen/mouse 🖱️
• Tablet support (especially ipad) using custom CSS
• HTML 5
• 100% vanilla Javascript (ES6)

How It Works

• The game generates 10 random maths problems one-by-one.
• It randomizes the numbers with a a number range of 1-11 for the first number and 1-30 for the second number

Children do not know the validity of basic mathematical proofs that adults take for granted. Also, negative-numbers can be quite tricky (too abstract) for young kids. Considering this the game is consciously designed to never generate problems where the answer is less than 0.

a + b == b + a

(This proof is self-evident for adults. But not for young children)

Usage

1. Click Start-button to Start the game
2. Enter digits by clicking on the buttons
3. Submit your answer using the 'DONE'-button
4. Game ends after 10 rounds

Development

The code is written using OOP (Object Oriented Programming) and uses the MVC-pattern (Model View Controller).
