Scratch Garden - Loops

What are loops?
They are instructions that repeat
What are loops?
They are instructions that repeat
What are loops?
They are instructions that repeat
What are loops?
They are instructions that repeat

Computers love to repeat things
And they never get bored!
Loops tell them what to repeat
And repeat some more!
And loops will also help
To save a lot of time
By repeating many things
So you don't have to keep writing
Line after line, after line, after line, after line

Now let's say you got a robot friend here
And you want to teach it to climb the stairs
You can't just say go climb those stairs
Cuz' it's not gonna know what to do when it's there
You gotta be specific, give it a try

Left leg up, forward, down
Right leg up, forward, down
Left leg up, forward, down
Right leg up, forward, down
Left leg up, forward, down
Right leg up, forward, down
Left leg up, forward, down
Right leg up, forward, down
Left leg up, forward, down
Right leg up, forward, down
Left leg up, forward, down
Right leg up, forward, down
I did it!

Well that's all good, the robot got to the top
But hold on a minute, that's right stop!
You said a lot of the same things again and again
Is there a better way to say everything?
Yes there is, that's where a loop comes in
Ah thanks loop, what a great friend!
Instead of writing everything many many times
You put it in a loop and write it one time
Set up a loop, put the stuff inside
Then there's only one thing left to decide
That's to tell the loop how many times to repeat
Yep that's it, the loop is pretty much complete
So let's return to our robot climbing the stairs, OK
We got the steps in a loop And soon it's on it's way
But let's add other stuff in the loop for fun today
How about we get the robot to shout hooray!

Alright, let's run the loop and see what happens

Left leg up, forward, down
Right leg up, forward, down, hooray!
Left leg up, forward, down
Right leg up, forward, down, hooray!
Left leg up, forward, down
Right leg up, forward, down, hooray!
Left leg up, forward, down
Right leg up, forward, down, hooray!
Left leg up, forward, down
Right leg up, forward, down, hooray!
Left leg up, forward, down
Right leg up, forward, down, hooray!

What are loops?
They are instructions that repeat (Three more)
What are loops?
They are instructions that repeat (Two more)
What are loops?
They are instructions that repeat (One more)
What are loops?
They are instructions that repeat (No more)
