What this worksheet teaches

• 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.
• Build vocabulary for basic computer terms like file, folder, icon, and cursor.

How to use this worksheet

Work this sheet in two short sittings rather than one long one. Do the labeling and matching questions first, then take a five-minute break to actually open a folder or type a sentence on a real device before finishing the vocabulary questions. Grade 3 students remember computer terms far better right after they have used the thing the word refers to.

Sample questions from this worksheet

1. MCQ: The CPU stands for ______.
2. MCQ: The monitor displays ______.

Frequently asked questions

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.

Is this worksheet aligned with a specific computer science curriculum?

It covers foundational computer literacy concepts (hardware vs. software, input vs. output, common terminology) that align with typical Grade 3 computer basics / digital literacy standards used across most school curricula.
