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.
