A short presentation I'm giving to the 4th graders at May Howard Elementary before introducing them to Hackety Hack.

1. CODE!

2. What’s Code?

3. It’s words that tell a
computer what to do.

4. But, humans can read
it too!

5. Code looks something
like this:

6. class Dog
attr_accessor :color, :size
def bark
“woof!”
end
end

7. I’ll show you how that
works later… remind me.

8. What’s it like coding
all the time?

9. FUN!

10. What’s The Web?

11. Billions of computers
listening for requests.

12. And responding
with… responses!

13. How it works

14. How It Works
•
Your computer makes a request to an address http://amazon.com
•
A thing called a DNS server says “Hey, that’s this
computer” and your computer sends that computer
a request.
•
That computer gets the request and answers it.
•
Just like a game of telephone.

15. And it all works

16. CODE!

17. Are you ready to write
some?!

18. ME TOO!
