    Hour of code

    This 20-hour course introduces core computer science and programming concepts. The course is designed for use in classrooms for grades K-8, but it is fun to learn at all ages.

    Hint :

    Google the names of the presenters and find out why they are famous. You might be suprised at what they do ...

    It builds on the previous introduction in the one hour of code.

    The programming language we will use from the hour of code site is called Blockely.  if you look to the right of the screen, you can click on the show code window and see the javascrip commands "under the hood".

                                            Completing this course is a mighty achievement.

                                            Remember this. We live in an age where most adaults agree kids know much more about computers than they do.

                                            Completing this course makes you a lot smarter in proper computing than them.
