Number Chart 1-20

Help build your students’ number sense skills with these free printable PDF number charts for the numbers from 1 to 20. 

What is a 1-20 Chart? 

A 1-20 Number Chart is a visual representation of the numbers from 1 to 20 that is commonly used by young children while learning numbers, counting, and basic place value concepts. The number chart features the numbers 1 to 20 arranged across five columns and four rows. 

The 1-20 chart is a smaller version of the classic hundreds chart. 

What are Number Charts Used for in the Classroom? 

Print a set of these 1-20 number charts to have in your classroom as an easy reference for students to grab. I suggest laminating the number charts for extra durability or placing them in dry erase pockets or heavy duty sheet protectors which will allow students to write and erase them over and over. 

MATH = LOVE RECOMMENDS…

I cannot imagine teaching math without my dry erase pockets! They instantly make any activity more engaging and save me countless hours at the copy machine since I can use the same class sets of copies year after year.

Here are my current go-to recommendations:

• 8.5 x 11 Inch Dry Erase Pockets from Puroma
• 11 x 17 Inch Dry Erase Pockets from C-Line Products
• Expo Dry Erase Markers

These number charts can be used as an alternative to a number line. Students can model basic operations on the number chart using small manipulatives or counters. 

They are also a great way to help students work on their number recognition skills. You could make cards for students to flip over which feature numbers written in word format or numbers represented on ten frames/double ten frames. As students turn over each card, they could mark the number off on their 1-20 chart. 

One of my favorite way to use number charts in the classroom is to discover patterns within the numbers. An example of this would be to have the students color all of the squares with even numbers one color and all of the squares with odd numbers another color. 

There are so many different ways to use this printable numbers chart in math centers with elementary school children. 

Need more than 20 digits? I have also created a free printable 1-30 number chart collection.

Blank Number Chart 1-20

​Do your students need practicing writing their numbers from 1 to 20?

I created a set of blank charts that you can print and have students fill in. The first version of the blank 1-20 chart has the numbers 1 and 20 filled in already. Students must write in the numbers from 2 to 19. 

I also created an alternate version which has all twenty boxes blank. 

Fill in the Blank 1-20 Number Charts

I also created a set of four different fill in the blank 1-20 number charts for students to use to practice writing their numbers from 1 to 20.

Some of the numbers are filled in already. Students must work to figure out what the missing numbers are. This is a fun way to fit in some number writing practice.
