Hello my amazing Grade 2 friends! 🎉
Today we're going on a super fun measurement adventure! We'll discover the difference between Standard and Non-Standard units. You are going to be measurement superstars!
📐
Standard Units
🖐️
Non-Standard Units
What is Measurement? 🤔
Measurement is how we find out how long, how heavy, or how much something is!
📏 Length
⚖️ Mass
🪣 Capacity
We use different tools and units to measure things every day.
🍎 How long is this apple?
🧸 How heavy is my teddy?
🥛 How much water is in my cup?
There are TWO kinds of units… Let's explore them! ✨
Non-Standard Units 🖐️
Non-standard units are things we use that are not always the same size — like your hand, your foot, or a paper clip!
🖐️
Your Hand Span
My hand is different from yours!
👟
Footsteps
Big feet vs small feet = different answers
📎
Paper Clips
Different sizes of clips give different results
🧱
Cubes or Blocks
Fun but not the same every time
"These are super fun for quick estimates in our classroom!" — Miss Grok
The Problem with Non-Standard Units 😕
If you and your friend both measure the same desk with your hands… you might get different answers!
👦 My hand = 18 hand spans
❌
👧 Your hand = 22 hand spans
That's why we need something that is ALWAYS the same! ✨
Standard Units 📏
Standard units are special units that are the exact same size everywhere in the world!
📏
Centimetres (cm)
For length
⚖️
Grams & Kilograms
For mass / weight
🪣
Millilitres & Litres
For capacity
Rulers, scales, and measuring cups use standard units so everyone gets the same answer! 🎉
Standard vs Non-Standard — Side by Side!
Non-Standard 🖐️
✅ Fun and easy
❌ Different people get different answers
❌ Not good for sharing with others
Standard 📏
✅ Always the same
✅ Everyone gets the same answer
✅ Perfect for real life (shops, building, cooking)
Real-Life Examples
Buying new shoes in a store → we use centimetres (standard)
👟
Cooking a recipe → we use millilitres and grams (standard)
🍪
Measuring the classroom floor for a game → we might use footsteps first (non-standard) then check with a metre stick (standard)

Let's Try It Together! 🧪
Try Non-Standard
Measure this desk with your hand spans!
Try Standard
Now imagine using a ruler in centimetres
See how standard units are more reliable? You're doing amazing! 🌟
Why Both Are Important
Non-standard units are super fun for exploring and estimating in class.
Standard units are super important when we need to be exact and share our measurements with the whole world!
We use BOTH — just like real scientists and builders! 🧪🏗️
Quick Check – You Are a Measurement Superstar!
Is a ruler a standard unit? 📏
Is your foot a standard unit? 👟
Are centimetres the same everywhere? 🌍
Do all children have the same hand span? 🖐️
You Did It! 🎉
🏆
You are now a Grade 2 Measurement Champion!
You understand when to use non-standard units for fun and standard units for accuracy.
You can measure anything in the world now! 🌍
