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 part is the brain of the computer?
2. MCQ: Which part shows the output?

Frequently asked questions

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.

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.
