How to use these worksheets at home

• Do one theory sheet and one hands-on-at-the-computer follow-up each week. Computer Science at school splits neatly into 'know it' and 'try it'.
• Print the labelling sheets (parts of a computer, keyboard rows, browser window) and let your child match them to your actual laptop or tablet.
• For every command or short program, encourage typing it out on the machine — reading code and writing code are different skills at every age.
• Re-print the vocabulary sheets before unit tests — CBSE Computer Science paper 1 is heavy on definitions and full forms (RAM, ROM, CPU, HTML, URL).
