What is Number Theory?
Number theory is like being a number detective!
It's the study of whole numbers and their special relationships. We'll explore prime numbers, factors, multiples, and divisibility rules - all the tools that help us understand how numbers work together.
Key Concepts to Remember
1️⃣ Factors: Numbers that divide exactly into another number
2️⃣ Multiples: The "times tables" of a number
3️⃣ Prime Numbers: Numbers with exactly two factors (1 and itself)

Parent Tips 🌟
- Make it a game: Challenge your child to find prime numbers in license plates or house numbers during car rides.
- Use household items: Use buttons or coins to physically group items and demonstrate factors and multiples.
- Connect to real life: Show how number theory helps with sharing equally (factors) or scheduling events (multiples).
