What Is a Number Chart in Math?

A number chart as a list of numbers that are written in a particular numerical order. 

For example, if natural or counting numbers from 1 to 10 are listed in the form of a grid, it forms a number chart 1 to 10. Similarly, a number grid 1 to 100 would contain all the numbers from 1 to 100.

A number chart is a graphical representation of numbers arranged in a specific order. It helps in visualizing number patterns, sequences, and relationships. Number charts are valuable tools for teaching counting, number recognition, and basic mathematical concepts. They are often used by teachers to aid in early number learning.

A number chart does not necessarily have to be a list of natural numbers or whole numbers. It can be a list of even numbers, odd numbers, and so on.

Types of Number Charts

There are different types of number charts that help kids in identifying the number patterns. Following are the different types of number charts:

Even Numbers Chart

Even numbers” are numbers divisible by 2. 

Examples: 2, 4, 6, 8, etc.

Here’s a number chart representing even numbers from 1 to 20:

Odd Numbers Chart

The numbers that are not divisible by 2 are called “odd numbers.” 

Examples: 1, 3, 5, 7, and so on.

Here’s a number chart representing off numbers from 1 to 20:

Odd numbers chart 1 to 20

Prime Numbers Chart

Prime numbers have only two factors, 1 and the number itself. 

Example: 2, 3, 5, 7, 11, and so on.

(0 and 1 are not prime numbers.)

Here’s a number chart representing prime numbers between 1 to 20:

Composite Numbers Chart

Composite numbers are simply the numbers that are not prime. Composite numbers have more than two factors.

Example: 4, 6, 8, 9, 10, and so on.

(0 and 1 are not composite numbers.)

Natural Numbers Chart

Natural numbers are used for counting or ordering. Natural numbers start from 1. They do not include 0.

The chart that represents these numbers is known as the natural numbers chart.

How to Make a Number Chart

We can create a number chart by using a few simple steps. 

  • Decide the Range and Pattern: Determine the range of numbers you want to include in your chart. For instance, you might choose to create a chart for numbers 1 to 100 or a chart of multiples of 6 between 1-100.
  • Prepare a Grid: Draw a grid on a piece of paper or use a digital tool. Divide the grid into rows and columns based on your chosen range. Label the rows and columns with appropriate headings.
  • Fill in the Numbers: Begin filling in the numbers in numerical order, starting from the first row and moving across the columns. For example, the first row might contain numbers 1 to 10, the second row 11 to 20, and so on.
  • Maintain Order: Ensure that you place the numbers in the correct order, following the sequence as you move across the rows and columns.
  • Add Visuals (Optional): To make the chart more engaging, you can use colors, shapes, or illustrations. These can help highlight patterns or make the chart visually appealing, especially for young learners.
  • Label the Chart: Add a title to your number chart that indicates the range of numbers it represents. This helps viewers understand the purpose of the chart.

Number Chart in Words

We can also write the numbers in words so that it becomes easy to understand how to read the numericals. 

The below chart shows the numbers from 1 to 20 along with the number words.

Number Chart Patterns

We observe different patterns in number charts such as even numbers, odd numbers, counting by 3’s, counting by 10’s and so on. 

Here’s a number chart representing the skip counting by 3’s pattern.

Facts about Number Charts

  • Number charts help kids learn counting and number sequencing.
  • They provide a visual representation of number patterns and relationships.
  • These charts assist children in recognizing numerals and understanding numerical order.
  • Number charts can be used to introduce addition, subtraction, and skip counting.
  • Kids can identify patterns, even and odd numbers, and multiples using number charts.
  • Number charts are available in various formats, such as grids, tables, and interactive digital versions.

Conclusion

In this article, we explored the concept of number charts, which serve as valuable tools for teaching counting, number sequencing, and basic math skills to kids. Number charts offer a visual way to understand number patterns and relationships. We learned patterns in number charts along with different types of number charts. To reinforce our understanding, let’s engage in solving examples and practicing MCQs.

Solved Examples on Number Charts

1. Find the pattern for the number chart given below.

Number chart showing skip counting by 9’s

Solution: 

The numbers marked in the number chart are:

9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99. 

It shows skip counting by 9’s.

2. Draw a number chart representing the skip counting by 4’s pattern.

Solution

To represent skip counting by 4’s, we highlight the following numbers:

 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 and so on.

3. Write the missing numbers and label the given number chart.

110120130
160170180
220240
300

Solution: 

The ones digit of all the numbers are 0.

Also, the difference between any two consecutive numbers is 10.

Thus, the chart shows the skip counting by 10’s pattern. 

After filling missing numbers, we get:

1020304050
60708090100
110120130140150
160170180190200
210220230240250
260270280290300
