What Are Tens and Ones?
Numbers are like building blocks!
Numbers from 10 to 99 are made of tens and ones. A ten is worth 10, and a one is worth 1.
We can break numbers apart into tens and ones, or put them together to make bigger numbers!
How to Convert Between Tens and Ones
1️⃣ Count how many tens and ones you have
2️⃣ Remember that 1 ten = 10 ones
3️⃣ Add them together or break them apart

Parent Tips 🌟
- Use household items: Count groups of 10 items (like crayons or buttons) to show tens, then count single items for ones.
- Play store: Use dimes (tens) and pennies (ones) to practice exchanging money, which helps understand place value.
- Make it physical: Have your child jump 10 times for each ten and 1 time for each one to feel the difference physically.
