What this worksheet teaches

• 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).
• Practice matching everyday computer tasks (typing, printing, browsing) to the device or program used to do them.

How to use this worksheet

Start by asking your child to name every computer part they can see in the room before they read a single question - this shows you what vocabulary is already secure and what is still guesswork. Then work through the sheet. Children at this age often mix up 'monitor' and 'computer', so when that happens, tap the screen and then the box or laptop base so the difference is physical rather than verbal.

Sample questions from this worksheet

1. MCQ: Which part protects the internal components?
2. MCQ: Which part shows moving images?

Frequently asked questions

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.

My child has never used a computer at school. Is this worksheet still appropriate?

Yes. This worksheet is designed to introduce Grade 3 students to basic computer vocabulary and concepts from the ground up, so no prior classroom computer experience is assumed.
