Rocket wants pancakes. The recipe steps below got mixed up. Put them in the order they should happen, first to last.
PANCAKE RECIPE
You can't pour batter you haven't mixed. You can't flip what isn't on the pan. End by EATING (definitely not first!)
?Mix flour, milk, and eggs in the bowl
?Flip when bubbles appear
?Eat the pancake
?Pour batter into the pan
?Heat the pan on the stove
?Get out a bowl and a pan
WHY THIS EXERCISEReal code has dependencies. You have to do the early steps before you can do the later ones. Programmers call this 'order of operations.'
◇ PARTNER MOVE
Read your order out loud to a partner. Did anything sound silly? Fix it before you flip the page.

?Climb into bed
?Put on pajamas
?Read a book
?Turn off the light
?Brush teeth
WHY THIS EXERCISEDaily routines are perfect examples of sequences. Programmers build big programs by chaining simple, predictable sequences like this one.
