Example 2: 

Example 3: Megha has 4 dolls. She needs as many dresses as she has dolls.
So how many dresses she needs for them?

Now watch a fun video on What is As Many As:

Can You Count?

Let us count the number of toffees given below and learn how to write the numbers.

What is More or Less?

More means greater and less means smaller. 

Example 1: Look at the picture given below. Can you tell which is more and which is less?

There are 5 butterflies and 2 plants

So, there are more butterflies and less plants

Example 2:  Look at the picture given below. Can you tell which basket has more fruits?

The basket on the left has 9 fruits

The basket on the right has 2 fruits

So, there are more fruits in the basket on the right

• In the numbers 3 and 2, we know that 3 is greater than 2.  This means,

• We can also say 2 is less than 3. This means,

Let's watch a video to learn the concept of More and Less:

Can you Count and Match?

Count the number of fruits in each row. Draw a line to match it with the correct number.

Get ready to watch a video to learn Count and Match:

One to Nine

One

1 is a special number that comes first when we start counting. We can think of it as the very beginning! 

Two

The number 2 is also a special number that we use to count and describe things. It tells us how many things we have or how many there are of something.

Example 1: Make a group of 4.

Example 2: Make a group of 7.

What are Missing Numbers?

A series or sequence where a number is missed is known as a missing number sequence. 

Look at the example given below. Numbers given are 1, ___, ___, 4, ___, ___, 7, ___, ___.

We just learned the counting above, so we know that the correct series will be 1, 2, 3, 4, 5, 6, 7, 8, 9.

What is Zero?

Let's understand the concept of zero with the help of an example.

How many chocolates do you see in the given picture?

If you give these 2 chocolates to your best friend, then how many chocolates will be left?

There will be 0 chocolates left.

Zero

Odd and even numbers

• Some numbers are called even numbers.
  An even number of objects can be put into pairs with none left over.
• Some numbers are called odd numbers.
  An odd number of objects always has 1 left over when the objects are put into pairs.

Keywords: even, odd, pair, pattern
Example: Draw a ring around the correct word for 3.
Use some cubes to help you.

Ans: 1 pair and 1 left over. 3 is an odd number.
