What is Place Value?

• Place value tells us the value of a digit depending on its place in a number.
• Example: In 23 → 2 is in the tens place (20), 3 is in the ones place (3).

Tens and Ones 💛

• Tens (🔟): A group of ten ones.
• Ones (1️⃣): Single units.
• Example: 24 = 2 tens (🔟🔟) + 4 ones (1️⃣1️⃣1️⃣1️⃣)

How to Model Numbers

• Use blocks, sticks, or drawings to show tens and ones.
• Tens are shown as a long stick or bundle 🔟
• Ones are shown as single dots 1️⃣

Building Numbers 🏗️

• Count tens first, then ones to know the total number.
• Example: 36 = 3 tens (🔟🔟🔟) + 6 ones (1️⃣1️⃣1️⃣1️⃣1️⃣1️⃣)

Expanding Numbers ✨

• A number can be written as:
• 47 = 4 tens + 7 ones = 40 + 7

Why It’s Important 💡

• Helps us read, write, and compare numbers.
• Makes addition and subtraction easier.
