Mini Lesson

A computer is a tool that helps us work, learn, and create. To use a computer well, you need to know its main parts and how to manage the files you make.

Main Parts of a Computer

  • Screen (monitor) — shows you everything happening on the computer.
  • Keyboard — lets you type letters, numbers, and symbols.
  • Mouse — lets you click, select, and move things on the screen.
  • CPU (a chip inside the tower or laptop body) — the brain that runs all the programs.
  • Storage (hard drive or USB) — keeps your files safe so you can use them again.

What Is File Management?

File management means keeping your work organized on a computer. You create files, give them clear names, save them in the right folder, and close them when you are done.

Steps to Work with a File

  1. Open the application (e.g. a word processor or drawing program).
  2. Create a new file and give it a clear name.
  3. Type or draw your content inside the file.
  4. Save the file — use Ctrl + S (Command + S on a Mac) or the Save button so your work is not lost.
  5. Close the application when you have finished.

Guided Practice

Pick a word from the Trace menu and look at the model. Use Copy mode to write it yourself on the lined pad, or switch to Trace if you want to pass over the ghost letters. Tap 🔍 Bigger for a fullscreen practice canvas.

Tracing Pad

Tip: As you copy, think about how each word relates to today's topic.

Now type any 3 different words from the Trace menu above. Look back if you need to — this is typing practice, not a memory test.
