Computing, 4–6 years — 20 topics · MyLeoNes™ Kuks
20 computing topics written for 4–6 years — not a older text simplified. In teaching order, each a deck of five cards: the idea, why it exists, a worked example, the common trap and where you meet it.
Computing · 4–6 years
Breaking a big task apart
A large job becomes easier when it is split into small jobs that can be handled one at a time. This is a powerful way to plan a computer task.
Clear instructions
A computer cannot guess what we mean. It follows small instructions in the order we give them.
Computers are machines
A computer is a machine made by people to handle information and carry out tasks.
Computers can help different people
Some computer features change how information is seen, heard or controlled so more people can use it.
Counters that change
A computer can keep a number and change it when something happens. Scores, turns and collected objects all need this small but powerful idea.
Digital sound
A computer can turn a sound into stored measurements and turn them back into sound.
Fixing mistakes
When a set of instructions fails, we can test the steps and change the part that went wrong.
Hardware and software
Computers need both physical parts and the programs that tell those parts what to do.
How animation makes movement
Many still pictures shown quickly can make a character seem to move.
Icons and symbols
A computer can use a small picture to stand for an action or an idea.
Input and output
A computer receives something, does a little work, and gives something back. Children can spot this flow in buttons, cameras, tablets and toys.
Keeping personal information safe
Some information belongs only to you and trusted adults, so sharing it needs care.
Networks connect devices
A network lets devices send information to one another, sometimes across a room and sometimes across the world.
Patterns and repetition
A repeated instruction can be noticed as a pattern. Naming the pattern helps us make longer sequences without saying every step.
Pictures are made of tiny dots
A screen picture is built from many tiny coloured squares called pixels. Looking closely helps children connect a bright picture with the small pieces a computer controls.
Position on a screen
A computer can describe where something is on a screen. Knowing position helps it place, move and find characters, pictures and buttons.
Save and find information
Computers can keep information so it is available later. Children meet this idea when they take photos, save drawings or open a game again.
Sorting information
Computers handle many things by putting them into groups or an order. We can practise this with objects we can see and touch.
Touch and click
A screen can wait for a touch, click or drag, then show what happened. This is how people tell a digital tool what they want.
Yes-or-no choices
A program can check one fact and choose what happens next. This simple idea makes games, stories and toys react to what is happening.
