Number Chart
A number chart is a list of numbers written in a particular numerical order. For example, if counting numbers from 1 to 10 are listed in the form of a grid, it forms a number chart from 1 to 10. With the help of these number charts, kids can easily learn to identify numerals and the order of numbers along with the patterns that are followed between the numbers. In simple words, a number chart is a chart that shows the list of numbers in a systematic order. A number chart is not necessarily a list of natural numbers or whole numbers. It can be a list of even numbers, odd numbers, and so on.

Odd Numbers Chart
An odd numbers chart represents all the numbers that are NOT divisible by 2. For example, 1, 3, 5, 7, and so on.
Prime Numbers Chart
A prime numbers chart represents all the prime numbers that have only two factors, i.e., 1 and the number itself. For example, 2, 3, 5, 7, 11, and so on.
How to Make a Number Chart?
A number chart can be created using a few simple steps. Let us create a number chart for the numbers starting from 1 to 100 using the following steps.
- Step 1: Draw a grid of size 10 × 10.
- Step 2: Start writing the numbers starting from 1 in the first block and continue writing the subsequent numbers horizontally. To write numbers in a number chart, add 1 to the previous number to get the next number.
- Step 3: Fill the numbers correctly and as neatly as possible.

How to Make a Place Value Chart?
In order to make a place value chart, we can use the following steps:
- Step 1: Draw columns showing different periods according to the type of numeral system: ones, thousands, and so on. For example, if we want to make an Indian place value chart for nine places, we draw 4 columns showing the 4 periods: ones, thousands, lakhs, and crores.
- Step 2: Under each period, we draw sub-columns to show the different place values like ones, tens, hundreds, thousands, ten thousands, and so on.

And finally, under the period of crores, we place crore and ten crores.
How to Use a Number Chart?
To get a better sense of numbers, we use a number chart. We identify the pattern and sequence of numbers in it. For example, in the even number chart, all the even numbers are placed starting from 2. So, with the help of that, we can easily identify the missing numbers and generalize the rule to obtain the next number in the chart.
