What is a Number Chart?
A number chart can be defined as a list of numbers arranged in a particular order. Number charts are often created in a format resembling a grid. There are various kinds of number charts, such as even number charts, odd number charts and prime number charts.
What is an Even Number Chart?
A chart with even numbers consists of a list of even numbers that are divisible by 2. For example, 2, 4, 6, 8, 10 and the even numbers that occur subsequently in this sequence are arranged on a grid.
What is an Odd Number Chart?
A chart that has a list of odd numbers consists of a list of odd numbers that are not divisible by 2. For example, 1, 3, 5, 7, 9, and a list of numbers that appear in this sequence are just like even numbers arranged in a grid pattern.
Odd Numbers between 1 to 100:
What is a Prime Number Chart?
As we know, a prime number is a number that has only two factors, 1 and the number itself. Thus, a chart with prime numbers consists of numbers that have just two factors. For example, the arrangement of 2, 3, 5, 7, 11 and this sequence in a grid pattern.
What do we do to Prepare a Number Chart?
You can prepare a number chart in the following way:
Create a grid with 10 rows and 10 columns. Then start writing the numbers from 1 to 100 in a chronological order. Your number chart should look like this:
Solved Examples
Example 1: Can you write the numbers that lie between 30 to 40?
Solution:
You can take the help of a number chart to solve this problem.
As we can see, the numbers that lie between 30 to 40 are 31, 32, 33, 34, 35, 36, 37, 38, 39 and 40.
Example 2: In the following number chart, find the following:
a. Find a number that is 5 greater than 32
b. Find a number that is 20 greater than 40
c. Find a number that is 12 lesser than 22
d. Find a number that is 8 lesser than 98
e. Find the numbers that are greater than 65 but less than 70
Solution:
Let us look at a number chart to answer the following questions.
a. From the chart, we can see that the number that is 5 greater than 32 is 37.
b. From the chart, we can see that the number that is 20 greater than 40 is 60.
c. From the chart, we can see that the number that is 12 less than 22 is 10.
d. From the chart, we can see that the number that is 8 less than 98 is 90.
e. From the chart, we can see that the numbers that are greater than 65 but less than 70 are 66, 67, 68, and 69.
Example 3: Monica is preparing a number chart but has missed out a few numbers. Can you help her with finding the numbers?
Solution:
From the blanks in the number chart, we can see that some of the numbers are missing. Let us add the missing numbers.
In the first row, 4 is missing.
In the second row, 7 is missing.
In the third row, 14 is missing.
In the fifth row, 16 and 19 are missing.
Number charts are useful for students as they can learn about numbers, understand how they are placed and their importance.
