Block coding is a way of programming. It makes use of the lexical structure of source code and a computer’s blocks. A program can’t run if it doesn’t have a corresponding block for each operation. It also allows for more flexibility when it comes to reusing blocks. This is particularly useful when the program is large and has many different components. In addition, it is easier to maintain and extend.
Kids who learn block coding usually start out with animations. This is simple animation that includes one screen with sound and motion. From there, you can move the blocks around to create more complicated animations that include multiple characters, speech bubbles, music, and a variety of kinds of motion. Most children will learn block coding while using a robotics kit. Some of these kits allow you to choose which block-coding language to use for your kids’ project.
