What is Expanded Form?
Numbers can be stretched out to show the value of each digit!
Expanded form breaks a number into hundreds, tens, and ones. Today we'll learn how to put these parts back together into standard form.
How to Convert from Expanded Form
1️⃣ Find the hundreds (like 200 or 500)
2️⃣ Find the tens (like 30 or 70)
3️⃣ Find the ones (like 4 or 9)
4️⃣ Add them all together to make the whole number!

Parent Tips 🌟
- Use real objects - Count out 100 pennies, 10 dimes, and 1 pennies to physically show how expanded form works.
- Make it a game - Write expanded forms on index cards and have your child "decode" them for points.
- Connect to money - $100 bills, $10 bills, and $1 coins make perfect real-world examples of hundreds, tens, and ones.
