You Already Think Like a Programmer

Welcome to AP Computer Science A. No experience needed today — you already have the three skills this class runs on. Prove it below. Every class starts with a Do Now like this one: work quietly, finish all four, and the page tells you when you're done.

1Skill: putting steps in orderTO DO

A program is just steps in the right order. Click these sandwich-making steps in the order a computer would need them:

4Your turn: why are you here?TO DO

    
In this class you will build games, apps, and programs that solve real problems. What is one app, game, or piece of technology you wish existed — or wish you could build? (There is no wrong answer. We'll share a few out loud.)

    
    
And your name, so Mr. Babb knows who dreamed it up:

    
    
    

  


  
🎉 FOUR FOR FOUR — you sequenced, you thought literally, you caught a one-character difference, and you brought an idea.
That's programming. Welcome to AP CS A.
Sit tight — we'll share some answers to #4 in a minute.
