Understanding Tens and Ones
Numbers are like building blocks!
Every number from 10 to 99 is made up of tens and ones. The tens tell us how many groups of ten we have,
and the ones tell us how many extra single blocks we have. Let's learn how to break numbers apart!
How to Write Numbers as Tens and Ones
1️⃣ Look at the number (like 24)
2️⃣ The first digit is how many tens (2 tens = 20)
3️⃣ The second digit is how many ones (4 ones = 4)
Let's Practice Together!
Example 1: The Number 36
Let's break down the number 36:
Tens (30)
10
10
10
Ones (6)
1
1
1
1
1
1
So, 36 = 3 tens and 6 ones!

Parent Tips 🌟
- Use everyday objects: Count groups of 10 items (like crayons or buttons) to show tens, then count extra ones separately.
- Play place value games: Write a two-digit number and have your child jump the tens (big jumps) and ones (small hops).
- Make it visual: Draw sticks for tens (| = 10) and dots for ones (• = 1) to represent numbers on paper.
