Sorting information — Computing, 4–6 years
Computers handle many things by putting them into groups or an order. We can practise this with objects we can see and touch.
Put alike together
Sorting means putting things in groups or arranging them in an order. We might group buttons by colour, or put three numbers before seven. A computer sorts information so that finding it is easier.
Why sort?
If every toy is mixed in one huge box, finding a red car takes time. Groups and order make the search smaller. Computers use this idea because they may need to find one item among thousands.
Sort the buttons
There are five buttons: two blue, one red, and two yellow. First we make a blue group, a red group, and a yellow group. Then we count them: blue two, red one, yellow two. The groups are now easy to check.
One rule at a time
A shiny button may seem to belong with other shiny buttons, even if we were sorting by colour. That is a reasonable choice, but it uses a different rule. We must decide the rule first and use it for every object.
Finding things
Libraries group books, shops arrange products, and a photo app can group pictures by date. These systems do not understand every picture like a person does; they use chosen features, such as colour, name, or time.
