Printable Number Line to 20

Last updated: August 28, 2026 by the Homemade Gifts Team

A printable number line to 20 gives early learners a visual way to explore counting, number order, addition, subtraction, and more. Kids love to count–how old they are, how many toys they have, the coins in their piggy bank, or even how many days until their birthday. As a teacher, I love using that natural curiosity to help kids visualize on the number line what those numbers actually mean and how they relate to one another.

Number lines are especially helpful because they turn numbers into something kids can see, point to, and move along. Teachers, parents, and other caregivers can use them to guide early math practice while giving kids a tool they can eventually learn to use more independently.

Number Line to 20

These printable number lines give kids several ways to work with numbers from 0 to 20, including filling in missing numbers and practicing skip counting by 2s. Most focus on positive numbers, while one extends from -20 to 20 to introduce the idea that numbers can continue below zero. This can be a great next step for kids who are ready to explore how negative and positive numbers relate to each other on a number line.

How Do You Use a Number Line to 20?

A number line to 20 can be used for much more than simply learning number order. With a few simple activities, you can use it to help kids count, solve early math problems, and become more comfortable working with numbers.

How to Practice Number Recognition

Before kids can work confidently with numbers, they need to recognize them without always counting from 1 to figure out which is which. Call out a number and have your child find it on the number line, cover it with a counter, or point to it as quickly as they can. You can also reverse the activity by pointing to a number and having them tell you its name.

How Do I Help My Child Count to 20?

For kids who are learning to count to 20, start by saying the numbers together while pointing to each one on the number line. Add manipulatives like blocks, buttons, or small toys so they can count out a matching quantity for each number. This helps kids connect the number they see with the amount it represents. As they become more confident, let them take over the counting and build each quantity on their own.

How to Teach Addition and Subtraction to 20

A number line can help kids see that addition means moving forward and subtraction means moving backward. Start with small problems like 5+3 by placing a finger or small toy on 5, then making three hops to land on 8. Let kids move the marker themselves and count each hop aloud so they can connect the math problem with what is happening on the number line.

How to Introduce Negative Numbers

Once kids have a strong number sense with counting above 0, the -20 to 20 number line can show them that numbers continue past zero. A number line to 20 with negative and positive numbers makes this easier to visualize: ask kids to imagine riding an elevator, where the ground floor is 0, floors above ground represent positive numbers, and floors below ground represent negative numbers. Move along the number line as the “elevator” travels up and down so kids can see how numbers on both sides of zero relate to each other.
