In a nutshell: Place value tells us the value of each digit, and patterns help us make predictions.
## Understanding Place Value
Each digit in a number has a place. In the number 14, the 1 is in the "tens" place, and the 4 is in the "ones" place. Place value helps us know how big a number really is.
## Exploring Number Patterns
Patterns are everywhere in math! You might see numbers go up by 1, 2, or 5 at a time. Spotting patterns helps us predict what comes next.
## Using Place Value and Patterns
Place value helps you read numbers like 23 or 45, and patterns help you count by twos or fives.
### Real-World Connections
Place value helps you read prices in a store, and patterns help you count groups of objects quickly.
