Numbers Count and Write the Number for Class 1 Maths

This learning concept will discuss count and write the number. Also, they will learn about skip counting by a particular number to make counting easy.

In this learning concept, the students will get to know about

• Forward counting
• Backward counting
• skip counting

This learning concept has explained to students by counting numbers using examples, and illustrations and a concept map are given at the end to summarize the idea. At the end of the page, two printable worksheets with solutions are attached for class 1 maths students to practice.

We use numbers to count anything. The numbers starting from 1 to 100 and beyond 100, are used for counting. These are called counting numbers.

There are mainly two ways of counting-

1. Counting Forward
2. Counting Backward

 

Forward Counting:

In counting forward, we count on by 1. Each number is one more than the previous number.

Example :

The frog is jumping on the numbers in forward direction. Each jump is one more than the previous jump.

• Forward counting is useful in finding numbers that come after.
• In forward counting, a bigger number always comes after a smaller number.

Example :

Here, we need to find out the number that comes after:

a. 17 b. 49

After counting forward the given numbers, we get:

 

Skip Counting

To count many things quickly, we count forward by the numbers other than 1. In this method, we keep adding the same number each time to the previous number.

Count forward by 2’s:

In this method, we count forward in 2. We count forward by skipping one number in between the previous and the next number.

Example :

Here, we need to count the numbers in forward direction by skipping one number in between like the following:

So, the correct answer is:

 

Count forward by 5’s:

In this method, we count forward by 5. We count forward by skipping four numbers in between the previous and the next number.

Example :

Count the five numbers from 5. We get the number 10. Again, count the five numbers from 10. We get the number 15.

So, the correct answer is:

• In the same fashion we can count forward in 3’s, 4’s, 6’s, 10’s, etc.

 

Backward Counting

In counting backward, we count down by 1. Each number is one less than the previous number. number decreases in backward counting.

• Backward counting is useful in finding numbers that come before.
• In backward counting, a smaller number always comes after a bigger number.

Example 1:

Here, we need to find the number that comes before:

a. 76 b. 63

After counting numbers backward, we get:

Sometimes we use backward counting to get the answers for the numbers, that are increasing.

Example 2:

Here, we need to count the numbers backward by skipping one number in between like the following:

So, the correct answer is:

 

Count backward by 2’s:

In this method, we count backward in 2. We count backward by skipping one number in between the previous and the next number.

Example :

Here, we need to count the numbers in backward direction by skipping one number in between like the following:

So, the correct answer is:

 

Count backward by 5’s:

In this method, we count backward in 5. We count in backward direction by skipping three numbers in between the previous and the next number.

Here, we need to count the numbers in backward direction by skipping four numbers in between like the following:

So, the correct answer is:

• In the same fashion we can count backward in 3’s, 4’s, 6’s, 10’s, etc.

 

Fun fact:

Forty is the only number name in English whose letters appear in correct alphabetical order.
