### In the lessons

In maths: a thing counted in a classroom, bought at a price, or a machine used for some time; «pupils per computer» is a sharing (division). In school: the computer room, computing lessons, typing and coding. In science: computers work very fast but only do what their program tells them. Safety: keep passwords secret and tell an adult if something online upsets you. Phrases: on the computer, computer game, computer program, turn on the computer.

### Note

Countable: a computer, two computers. Say «on the computer» (working on it), «at the computer» (sitting there). A counted item or a price; «pupils per computer» is a sharing (division). No clue by itself. A computer is not always right: it can only use what it is given.
