The hour of code

The last week in Informatics we learnt how to use a website called Khan Academy, in this website you can learn all about the subject you want. We chose to star a lesson in Khan academy about how to use codes to draw in the Computer, There are different steps on Khan Academy where you must complete the exercises to win points and go to the next level. It gets harder every time you achieve to complete a level. To learn about your subject you have videos, text explanations and some exercises, and if you complete the you win aproximatly 1000 points.

The first thing we learned in “the hour of code” is how to draw circles. We saw a video in which a girl taught us to use a specific codes to draw a round face. To do that you first have to write ellipse and in () you write some numbers which describe the exact position where the circle will be. She also showed us how to draw a rectangle by using rect(). As we got better we learned other codes for forms like to draw a line or a triangle.

Here is an image of some figures and its codes to draw them:

When we finnished practsing and learning to draw using codes, we had to choose between three different proyects to test our knowledge about the subject: a self potrait, a snowman or a wild animal. I chose the wild animal and I drew a piguin. In the prosses i lernad how to add colors to my drawing. To do that we use the comand fill() and that select a color.

Here is an example of the project of a snowman that my partner andI did:

Every time you complete a challenge you earn points and badges. Some badges I won are: challenger, programing scholar and tinkerer. I also won some “challenge patches”, these are special awards for completing topic challenges. Of this patches I won: the JS: Coloring, JS: Drawing, Hour of Drawing with Code Blocks and the Hour of Drawing with Code.

This is the Introduction video about the hour of code, it has the required information to improve in your work in Khan Academy:

Here is another video from Khan Academy where it explains what it is and what is use for:
