LESSON 10: Variables and Output

Today we are going to start to learns programming. First, we are checking out a software created by a Spanish student that will help children to learn programming concepts: Primary Code.

To understand what programming is, after an explanation, we open the tool Maker Makey, in which we started learning about simple things about programming.

INPUT AND OUTPUT

Input is anything you put into the computer like the mouse or the keyboard. Output are the things that come out of the computer like the screen or a printer. It will tell them how to write instructions on the screen. A variable is like a little box you put things into. The things you put into the variable will appear on the screen. Input is harder to understand, according to the teacher, but you introduce it into the variable and it shows in the screen.

SCRATCH

The following image shows the result of the proposed activity with the variables and how was the first contact with scratch.
