MATHMANIA – A SIMPLE CALCULATION GAME FOR KIDS

Learning by doing. Therefore, I would like to introduce to you an exciting but quite simple project to help you strengthen your knowledge of front-end web development. Also, you can use this project to have fun with children and encourage them to learn Math.

The technologies for this project are:

  • HTML5
  • CSS3
  • Javascript
  • Bootstrap 4 (optional)
  • AngularJS (optional)

In fact, this project is Math game. For each game, the player has to answer questions by doing calculations. The available calculations are addition, subtraction, and multiplication. For each answer, the system checks and provides the player with the correct calculation. After 10 questions, the game ends, shows final result, and allows the player to play again. In addition, the game shows the player’s progress on the top-right of the screen.

Below are some screenshots of the game.

Moreover, this project can be extended with features like division, saving best score, and timing.

By finishing this project, I hope that you will be familiar with fundamental front-end technologies such as HTML, CSS, and Javascript.
