What is a Number Line?
Number lines are like math roads that help us count and add numbers!
A number line shows numbers in order from left to right. We can use it to add by making "hops" from one number to another. It's like playing hopscotch with numbers!
How to Add Using a Number Line
1️⃣ Start at the first number
2️⃣ Hop forward the number of spaces you're adding
3️⃣ Land on your answer!
Let's Try Some Examples!
Example 1: 3 + 2 = ?
Let's solve 3 + 2 using the number line below!

We start at 3 and hop forward 2 spaces. Where do we land? 5! So 3 + 2 = 5!
Example 2: Your Turn!
Solve 4 + 3 using the number line. How many hops do you need to make?

Parent Tips 🌟
- Make it physical: Create a giant number line on the floor with chalk or tape and have your child physically hop along it to solve problems.
- Use small objects: Have your child move small toys or snacks along a drawn number line to visualize the addition.
- Play number line games: Create simple board games where players move along a number line by solving addition problems.
