Code Simple Programs Using Visual Blocks

Visual block coding lets you create programs by snapping together colored blocks instead of typing lines of text code. Each block represents an instruction. When you connect blocks in sequence, the computer follows them in order. Tools like Scratch use this approach, making coding accessible for beginners.

Types of Code Blocks

• Event blocks — trigger the program to start, e.g. "When flag clicked" or "When key pressed".
• Motion blocks — move or rotate the character on screen, e.g. "Move 10 steps".
• Control blocks — manage loops and conditions, e.g. "Repeat 10 times" or "If ... then ...".
• Looks blocks — change appearance or speech, e.g. "Say Hello!" or "Change costume".
• Sound blocks — play audio or music, e.g. "Play sound meow".

Logical Steps to Build a Program

1. Define what the program should do — decide the goal before you start building.
2. Choose and place the event block — this is the starting trigger for your program.
3. Add motion or action blocks — make the character move or do something.
4. Add control blocks — use loops or conditions to repeat or make decisions.
5. Test and fix any errors — run the program, observe what happens, and adjust.
