HTML/Javascript Canvas Fractions Game Tutorial
The Canvas HTML element tag can be used as the container to draw graphics on the fly usually via the use of Javascript functions for rendering and event management.
In today’s tutorial we touch on the functionality to draw an image on the canvas via drawImage() method. In the case of this tutorial that image contributes to the user answering some mathematics questions regarding fractions on a simulated “chalkboard”.
You may want to read more at HTML Canvas Reference as a generic reference, or here, at the tutorial javascript – How do I add a simple onClick event handler to a canvas element? – Stack Overflow.
As you can imagine, this HTML canvas element, new to HTML5, can be very useful for some practical client-side web functionality.

You’ll notice heavy use of the Javascript Math.random() function.
We hope you enjoy this tutorial as a live run.
Yes … you’ve reached the end … hope you have a good time practising your mathematics knowledge of fractions (there is advice, if you want to learn … you can get it when you give an incorrect answer)! We extend the visual aspects to the functionality when we revisit this posting on 11/05/2014.
