Learning about Loops

Warp blue

Time for a new book. Ben hands Roberto the next book.&nbsp; How do we programme a loop again?

“Turn the page and read the words 20 times

Gosh, Ben is getting tired. There must be an easier way to ask Roberto to read the story.

He could use a loop! A loop is an instruction that repeats!

Ben turns to the back of the book. This book has 20 pages. This means he has to ask Roberto to turn the page and read the words 20 times

What happens next? WOW Roberto read the entire book.

Wait! Roberto is still reading even though the book is finished! This book must be shorter than 20 pages. Let’s change the instructions

“Turn the page and read the words 12 times

“Ok great, now turn the page and read the words”

“Ok great, now turn the page again and read the words”

“Turn the page again and read the words”.&nbsp;

Oh, I remember, thinks Ben. Roberto has a computer inside.

Ben tries to make his instructions very specific.

Computers need very clear instructions, so let’s try again.

“Hey, Roberto, please bend down, pick up a book, stand up then read the words on the front cover”

Quick, maybe he can ask Roberto, his helper robot to help!

Using Loops with Ben and his helper Robot

In no time, Roberto and Ben had finished all the books. “DAD, I’m ready to go to the library now” Ben calls to Dad.

…. (Roberto stays silent and doesn’t move)

Challenge If you had a helper robot, how could you use a loop?&nbsp;

Tomorrow is Saturday. On Saturday’s Ben and his dad go to the library together. The only problem is, Ben still hasn't read all of the books he borrowed last time!
