Understanding Tens and Ones with Bundles
Place value is the superpower of our number system! The position of a digit tells us how much it is actually worth.

10
10
3 Tens = 30
5 Ones = 5
3 Tens + 5 Ones
= 35
Place Value: 3 bundles of 10 and 5 loose ones build the number 35.
1. What is a Ten?
When we collect 10 loose matchsticks or beads and tie them together with a ribbon, we have 1 Ten. 1 Ten = 10 Ones.
Visualizing: 2 bundles of 10 = 20. 4 bundles of 10 = 40. 9 bundles of 10 = 90.
2. Two-Digit Place Value Chart
In the number 63: the digit 6 is in the Tens place (value = 60), and 3 is in the Ones place (value = 3).
Rule: The rightmost digit is always Ones. The digit to its left is Tens!
💡 Key Learning Takeaways
- 10 ones combine to make 1 ten.
- The right digit is Ones; the left digit is Tens.
- Value of digit = digit × place.
🎯 Key Learning Takeaways
Tens and ones place values.
