What this worksheet teaches

• Recognize simple input and output devices and sort them correctly.
• Describe the steps of starting up, using, and safely shutting down a computer.
• Identify the main parts of a computer - monitor, keyboard, mouse, and CPU - and explain what each one does in simple terms.
• Understand the difference between hardware (parts you can touch) and software (programs that run on the computer).

How to use this worksheet

Because many Grade 3 students are still building hands-on comfort with computers, it helps to have an actual device nearby while completing this worksheet - even a phone or tablet works for pointing out a 'keyboard' or 'screen' in real life. Go through the worksheet together first, then let your child try labeling or answering on their own. If a real computer is available, pause and point out each part as it comes up in the questions.

Sample questions from this worksheet

1. MCQ: Which device shows text and pictures?
2. MCQ: Which part processes all the information?

Frequently asked questions

My child uses only a tablet at home. Will the mouse and keyboard questions confuse them?

They may take a little longer, and that is expected. Tablet-only users often have no mental picture of a cursor. Let them move a mouse for a couple of minutes before the worksheet, or draw an arrow on paper and slide it around to show what a cursor does.

Is there anything about online safety in this worksheet?

This sheet stays on parts, terms and devices rather than internet safety. If your child is already browsing, treat the vocabulary here as the groundwork - knowing what a file, folder and program are makes later safety rules such as 'do not open unknown files' actually make sense.

Does my child need to use a real computer to complete this worksheet?

No - this worksheet can be completed with pencil and paper alone. However, having access to a real computer or tablet nearby can help your child connect the terms and pictures to real objects they recognize.
