Boost Introduction: Enhance Engagement

🎯 Identified Problem

Upon analyzing the provided introduction script, several areas for improvement in error handling and child engagement were identified. Let's delve into these opportunities:

1. Reaction to Machine Discovery: Responses like "too beautiful / meh / I don't understand."

   • Current State: Only three fixed options, no differentiated management.
   • Problem: No tailored response to each child's feeling.

2. Question about the Number of Digits: "Do you remember how many different digits you saw?"

   • Current State: Handles three cases (9, 10, other).
   • Problem: Generic feedback for "other."

3. Question about the Maximum Count: "How high can we count now?"

   • Current State: Handles three cases (100, 99, other).
   • Problem: No progressive help, only binary feedback.

4. Lack of Interactivity: The child is mostly passive, just listening.

   • Need more moments where the child manipulates and discovers on their own.

Managing Responses - 3 ATTEMPTS SYSTEM

ATTEMPT 1: Simple encouragement

Answer: 9 (very common error)

"Hmm... not quite! 🤔"
"I understand why you think that!"
"You counted: 1, 2, 3, 4, 5, 6, 7, 8, 9... that's 9!"
"But... are you forgetting something? 😉"
"Think carefully and try again!"

Answer: 10 (correct!)

"BRAVO! 🎉🎉🎉"
"That's EXACTLY right! There are 10 different digits!"
"You didn't forget the ZERO! 👏"
"0, 1, 2, 3, 4, 5, 6, 7, 8, 9 = 10 digits!"
"Zero is a bit special, but it's VERY important!"
[Go to the next phase]

Answer: Other number (< 9 or > 10)

"Hmm... that's not it! 🤔"
"Do you want me to give you a hint?"
[Buttons: "Yes, a hint!" / "No, I'll try again!"]

ATTEMPT 2: Visual hint

If asking for a hint OR 2nd incorrect attempt:

"Okay, watch carefully!"
[Animation: Show the digits one by one]
"Here are ALL the digits that the machine can display:"
[Sequential display with pauses: 0... 1... 2... 3... 4... 5... 6... 7... 8... 9]
"Now, how many do you see?"
"Count them carefully! 👆"
[Possibility to click on each digit to count them]

If answering 9 again:

"Almost! But look at the FIRST digit! 👀"
"The one at the very beginning, before the 1..."
"It's the...? 🤔"

If answering 10:

[Celebration as above]

If answering something else:

"Not yet! But don't worry! 😊"
"Count with me!"

ATTEMPT 3: Guided counting

If 2 failures:

"That's okay! We'll count TOGETHER! 🤝"
"Look at the screen and count with me out loud!"

[VERY slow animation, each digit appears and stays for 2 seconds]

0 → "ZERO! It's the first one! Raise 1 finger! ☝️"
1 → "ONE! Now 2 fingers! ✌️"
2 → "TWO! 3 fingers! 🤟"
3 → "THREE! 4 fingers!"
4 → "FOUR! 5 fingers! ✋"
5 → "FIVE! 6 fingers!"
6 → "SIX! 7 fingers!"
7 → "SEVEN! 8 fingers!"
8 → "EIGHT! 9 fingers!"
9 → "NINE! 10 fingers! 🙌"

"There you go! Count your fingers: 10 fingers = 10 digits!"
"Do you understand now? 😊"
[No need to ask again, move on]

Summary messages (for all paths):

"So in total, we have 10 different digits!"
"0, 1, 2, 3, 4, 5, 6, 7, 8, 9!"
"The ZERO is a bit special..."

5. [Input field]

Managing Responses - 3 ATTEMPTS SYSTEM + EXPLORATION

ATTEMPT 1: Encouragement + light hint

Answer: 99 (correct!)

"BRAVO! 🎉🎉🎉"
"That's EXACTLY right! We can count up to 99!"
"You thought well!"
"Each roller can display 9, so: 9 and 9 = 99!"
[Move to the next phase]

Answer: 100 (very common error)

"Hmm... not quite! 🤔"
"100 is a very good number, but..."
"	...unfortunately the machine can't reach it for now!"
"Look carefully at the rollers..."
"What is the LARGEST digit on each roller? 🔍"
"Try again!"

Answer: 20, 50, 90, or other < 99

"You can go HIGHER than that! 📈"
"Look: each roller can go up to 9!"
"Fill BOTH rollers to the maximum!"
"What number does that make? 🤔"

Answer: > 100

"Woah, that's a lot! 😄"
"But unfortunately the machine can't count that high!"
"Look carefully: how many rollers are there? 👀"
"Only 2! And each roller goes up to 9!"
"Try again!"

ATTEMPT 2: Guided exploration

If 2nd error:

"That's okay! 😊"
"Do you want me to help you find it?"
[Buttons: "Yes, help me!" / "No, I want to try again!"]

If "Yes, help me!":

"Okay! We'll discover it TOGETHER! 🤝"
"Click △ to fill the FIRST roller to the maximum!"
[The child clicks up to 9]
"There! 9! That's the maximum for the first roller!"
"Now, click △ on the SECOND roller to fill it too!"
[The child clicks to display 9 tens, 9 units = 99]
"STOP! Look at the screen!"
"What number do you see? 👀"
[Let the child observe]
"It's 99! NINETY-NINE!"
"That's the MAXIMUM that the machine can display!"
"Now you know the answer! 😊"
[No need to ask again, move on]

If "No, I want to try again!":

"Okay champ! Last try! 💪"
"Hint: Look how much each roller can display at maximum..."
"First roller: ? (it can go up to 9)"
"Second roller: ? (it can go up to 9)"
"What number does that make in total? 🧮"

ATTEMPT 3: Visual demonstration

If 3rd error:

"No problem! I'll SHOW you! 👀"
[Automatic animation]
-  Roller 1 fills: 0→9
-  Text: "First roller: 9"
-  Roller 2 fills: 0→9
-  Text: "Second roller: 9"
-  Both flash
-  Large display: "99!"

"There! The maximum is 99!"
"Two rollers = 99 maximum!"
"Do you understand now? 😊"

Summary messages (for all paths):

"So, with TWO rollers, we can count up to 99!"
"That's MUCH more than 9!"
"We went from 9... to 99!"
"That's 90 more numbers! 🚀"
"But... if I want to count to 100 or more..."
"	...I'll need to modify the machine again! 🔧"
"Are you ready for the next part of the adventure? 🎉"

Duration: 3-5 minutes (depending on the number of attempts)

Objective: Understand the limit of 2 digits, never block the child.
