Hi again, Crew!
Yay! You came back.
Today, we pack a bag.
And we unpack it too!
Some steps can switch.
Time to pack a bag.
First, open the bag.
Then, put stuff in.
Last, zip it shut.
Some steps can switch.
Lunch box can go in first.
Or water can go in first.
Both work!
And then... back home!
Open the bag again.
Take out the lunch box.
Eat your snack!
That is how coders think.
Some steps must be in order.
Some steps can switch.
You pick the plan.
PACK AND UNPACK THE BAG.
- Tap a step.
- Then tap a spot.
- Open first. Zip in the middle. Snack last.
