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: Computers in schools are used for ______.
2. MCQ: Computers help drivers navigate using ______.

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.
