Week 01 · Monday: Sequencing (Code Crew G3)

Monday: Meet the Idea

ROCKET woke up and tried to put on socks BEFORE shoes. Easy. Then RAVEN tried to put on socks AFTER shoes. Stuck!

Computers are exactly like Raven. They do the steps in the order you give them. If the order is wrong, they get stuck.

Big Idea

A SEQUENCE is a list of steps in order.
Same steps, different order = different result.

Quick Try: Morning Steps

Put these steps in the right order. (On paper: write 1, 2, 3, 4. On screen: drag them.)

GETTING READY FOR SCHOOL

?Eat breakfast
?Put on backpack
?Wake up
?Brush teeth

WHY THIS EXERCISEA SEQUENCE is steps in a specific order. Computers run code the same way: top to bottom, one line at a time. If you put the steps in the wrong order, the program (or your morning!) doesn't work right.
