• Understand the difference between hardware (parts you can touch) and software (programs that run on the computer).

How to use this worksheet

If your child uses a tablet at home but rarely a desktop, expect the mouse and CPU questions to be the slowest ones. Before starting, let them hold a mouse and move the cursor for a minute or two. Afterwards, review any question they answered with a shrug rather than a wrong answer - a shrug usually means the object itself is unfamiliar, not that the concept is too hard.

Sample questions from this worksheet

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

Frequently asked questions

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.

Why does my child keep calling the monitor 'the computer'?

This is the single most common Grade 3 mix-up, because the screen is the part children actually look at. Point to the screen and say 'monitor', then to the laptop base or tower and say 'the computer that does the thinking'. After two or three repetitions with a real device, most children stop swapping the words.
