Coding, or computer programming, is your way of communicating with technology. It’s the new literacy you need to master to be successful in the coming decades. Like any form of communication, coding takes place through language. Just as there are many human languages (English, French, Mandarin, Spanish, and so on), there are many coding languages!

When coding, it’s important to teach kids the basics of setting and finding position. Setting the position of an object means assigning it coordinates to put it in a specific place onscreen. Finding the position of an object means identifying its coordinates to know where it’s located. Using pseudocode While each programming language uses its own structure for setting and finding coordinates, a typical pseudocode expression you may write to set the position of an object looks like this: setx x-coordinate sety y-coordinate Or setposition (x-coordinate, y-coordinate) To find the current position of an object, you can write pseudocode for each separate coordinate: x-position for the x-coordinate of the object, and y-position for the y-coordinate of the object.

Coding is fast becoming a skill that every child needs to be educated for in the 21st Century. But coding is taught at only a small fraction of schools, and often only at the high school level. Helping kids learn how to code also means you’re assisting them in developing a skill that is highly marketable and sets them apart from peers at school and later, in their careers.

After you and your young coder finish making your app, you can share it with anyone who has an Android device. Just go to your list of Projects (Projects  →   My Projects), check the box next to the app you want to publish, and click Publish to Gallery. The view from the Projects list to publish your app to the Gallery.

Your coder can provide flexibility to her programs by coding parameters to subprograms. For example, coding a square subprogram allows the program to draw a square of a defined size each time the subprogram is called. But what if you want the square subprogram to draw squares of differing sizes? By adding a parameter to the subprogram you can do just that.

As your young coder constructs his programs, he uses logic operations to make decisions about which code needs to execute, and under which conditions. The if-then statements he wants to construct may need to consist of more than one condition — they may need compound (multiple) conditions to execute the consequence.

Kids need to learn how to code all of the basics. Searching through lists is a very important task that you and your coder might want to have your program accomplish. Linear versus binary searching algorithms When it comes to lists, linear search is pretty straightforward. Essentially you start at the beginning of the list, and check to see if the first item is the item you’re looking for.
