Why does order matter?
Same blocks, different order, completely different ending.
Meet the block
Order matters in a program, like making a sandwich — bread first, then the filling. Same steps, wrong order, silly sandwich. The computer will never fix your order for you. It just does them the way you wrote them.
Move this block one place earlier and the whole journey changes.
See it work
Two programs, exactly the same five blocks. One picks up the key first. Watch them both.
Nothing was wrong with any of those blocks. The only difference was which one went first — and one fox is standing outside a locked door.
Your turn
Now you're the programmer.
Can you get the fox through the door?
Grab the 🗝️ first, then reach the 🚪.

How many ways in are there?
The key has to come before the door, but everything else is yours — go down first, or across first, or zigzag. Then try going straight right on purpose, just to hear the door refuse you.
For grown-ups
Sequencing — understanding that order changes outcome — is the first computational-thinking skill schools test for.

Make a game other kids can play
The blocks on this page are a first taste. In a Kubrio project your kid builds a real game — powers, triggers, levels and all — and other kids get to play it.
