What is a Number Line?
A number line is like a math road that helps us count, add, and subtract numbers!
It's a straight line with numbers placed at equal distances. We can use it to see how numbers relate to each other and solve math problems in a fun, visual way.
How to Use a Number Line
1️⃣ Find your starting number - Put your finger on the first number
2️⃣ Count the jumps - Move right to add, left to subtract
3️⃣ Land on your answer - The number you land on is your solution!
Let's Practice Together!

0
10
20
30
40
50
60
70
80
90
100
Start at 30. If you make 4 jumps of 10 to the right, where will you land?
Parent Tips 🌟
- Make it physical: Create a giant number line on the floor with tape and have your child walk the jumps for addition and subtraction.
- Daily practice: Use number lines when talking about temperatures, ages, or counting money to show real-world applications.
- Game time: Play "Number Line Hopscotch" where your child jumps to the correct answer to math problems you call out.
