What is a Number Line?
A number line is like a special path that helps us count and understand numbers!
It's a straight line with numbers placed in order from smallest to biggest. Today we'll explore numbers up to 30, which is more than all your fingers and toes put together!
How to Use a Number Line
1️⃣ Find the starting number
2️⃣ Move right to add numbers
3️⃣ Move left to subtract numbers
Let's Play with Number Lines!

Parent Tips 🌟
- Hopscotch counting: Draw a giant number line with chalk outside and have your child hop to different numbers while counting aloud.
- Daily practice: Use number lines when talking about daily activities - "If we leave at 3:00 and it takes 4 minutes to walk, what time will we arrive?"
- Make it tactile: Create a number line with sticky notes that your child can rearrange or remove to understand addition and subtraction.
