Why Learn Scratch
Computers are powerful tools that can be used for solving problems, completing tasks, watching movies, or playing games. However, the programs that we use on the computers must be written. Scratch will allow you to write your own programs and games that you can use or share with your friends.
While learning Scratch, you can also use skills that you learn in other classes such as math, music, or science. For example, you could write a calculator program, you could create a virtual piano, or you could write a program to simulate a scientific experiment.
