Opening Hook
Look at Our Lunch Menu
Your teacher is showing the lunch menu.
Don't say anything yet — just look carefully.
What numbers do you see? What is being counted? What information is being shared?

Lesson
What Is Data?
Data is information we collect by counting, measuring, or noticing things.
Data answers the question: "How many? How much? What kind?"
- 🍎 How many apples are in the basket? → data about counting
- 🌡️ How tall are the students in our class? → data about measuring
- ☀️ What is the weather each day? → data about noticing

Lesson
Data in Everyday Life
People collect data every day — even at school!
📅
Attendance
Counting who is here each day
🌤️
Weather Chart
Recording sunny, rainy, cloudy days
🍽️
Lunch Menu
Tracking food choices and counts
All of these are data! Someone is counting, measuring, or noticing — and writing it down.

Lesson
We Record and Organize Data
📝 Record
- Write it down right away
- Use numbers, check marks, or words
- Don't rely on memory alone!
🗂️ Organize
- Put it in order
- Make it easy to read
- Use a list, chart, or table
When data is organized, we can answer questions like: Which has the most? Which has the least? How many altogether?

Activity Help
What Counts as Data?
Ask yourself: "Is someone counting, measuring, or tracking something here?"
- 📆 A calendar — tracking days and dates
- 📏 A height chart — measuring how tall people are
- 📚 A library list — tracking books checked out
- 🌡️ A thermometer — measuring temperature
- ✅ A job chart — tracking who does what
Found something not on this list? Even better — tell us about it!

Share Time
Let's Share What We Found!
With your partner, take turns:
- 👆 Point to one of your data examples
- 🗣️ Say: "I found ___. It is data because ___."
- 👂 Listen to your partner's examples
- ⭐ Did you find any the same? Any different?
There are no wrong answers — if someone counted or measured it, it's data!

🧠
Brain Break — Clap-Count!
How many data examples did our class find together?
Count them on the board — then clap that many times!
Now — how many students are here today?
Jump that many times. Count out loud as you jump!
Those numbers you just used? That's data too! 📊

Big Idea
Why Does Data Matter?
Data helps us make decisions. Without data, we would just be guessing!
😕 Without Data
- Not sure how many lunches to make
- Don't know if kids are growing
- Can't tell what weather to expect
😊 With Data
- Make exactly the right number of lunches
- Track growth over time
- Prepare for weather patterns

Big Idea
You're Already a Data Scientist!
Every time you count, measure, or notice something and write it down — you're doing data science.
Have you ever counted how many people wanted pizza vs. pasta?
Noticed how many sunny days there were this week?
Recorded how many books you read?
That's data science.
