🟢 What is Place Value?

  • Place value tells us the value of a digit based on its position in a number.
  • Example: In 234, 2 = 200, 3 = 30, 4 = 4

🔢 Ones, Tens, and Hundreds

  • Ones (1️⃣): Single units
  • Tens (🔟): 10 ones make 1 ten
  • Hundreds (💯): 10 tens make 1 hundred

📦 Using Base-10 Blocks

  • 🟩 Small cube = 1 one
  • 🟦 Long rod = 1 ten
  • 🟥 Big square = 1 hundred

💡 How to Read a Number

  • Look at each digit and see its place value.

📝 Writing Numbers with Place Value

  • Use expanded form to show value:
