Put these sandwich steps in order!
To make a peanut butter sandwich: Spread peanut butter • Get bread slices • Put slices together • Open the jar. What order must these steps go in? Why can't you do them in any order?
Before you can do ANYTHING with a sandwich, you need something to put stuff ON.
What do you spread peanut butter onto?
You need to get the BREAD first because that's what holds everything!
The peanut butter is inside a closed jar!
Can you spread something you can't reach?
Opening the jar MUST come before spreading - you can't use what you can't access!
Once you have bread AND the jar is open, NOW you can spread!
This step DEPENDS on the first two being done.
That's called a "dependency" - it can't happen until other things happen first.
A single slice with peanut butter isn't a SANDWICH yet!
What makes it a sandwich? Two pieces of bread with filling between!
Putting slices together is always LAST because everything else must be ready.
Correct order:
1. Get bread slices - You need a surface to spread on!
2. Open the jar - Can't use what you can't access!
3. Spread peanut butter - Needs bread AND open jar first!
4. Put slices together - Creates the final sandwich!
Key insight: This is "dependency ordering" - some steps DEPEND on earlier steps being complete. You can't spread before opening (no access). You can't put together before spreading (nothing to sandwich!). Understanding dependencies helps with recipes, instructions, and problem-solving!

🧠 Thinking habits this builds:
- Understanding sequential dependencies
- Recognizing prerequisites
- Planning multi-step tasks
- Identifying what blocks what
🌿 Behaviors you may notice (and reinforce):
- Asking "what needs to happen first?"
- Explaining why one step must precede another
- Identifying blocked steps
- Planning before doing
How to reinforce: "You figured out the dependencies! That's how engineers and chefs plan complex tasks."
🔄 When ideas are still forming:
Children might not see why order matters until they imagine doing it wrong.
Helpful response: "What if you tried to spread on the bread BEFORE you got the bread? What would you spread onto?"
🔬 If you want to go deeper:
- What other recipes have strict step orders?
- Are there any steps that COULD be swapped?
- What's the dependency for "baking a cake"?
Key concepts (for adults): Sequential dependencies, prerequisites, critical path, procedural ordering.
