Is this your report card, Starry? Congratulations. 

You have come second in class.

What did you say?

You haven’t, of course you have.

Look, second. Oh… You think you have come 2 in class. 1,2.

No Starry, 2 is the cardinal number. 

Cardinal numbers are counting numbers.

They tell us “How many?” 1-2-3-4-5… are all cardinal numbers.

When things, objects, people are place in order we use ordinal number to tell their position.

                                                             

Let me explain!

Your friend Raj has got the highest marks.

He is number 1. He has stood first in class.

Then you, Starry are number 2. So you have come second.

Ria is number 3. She has come third in class.

And Asha is number 4. So she has come 4th.

What about Rahui, Starry?

He is number 5. So he is 5^th in class.

Notice the order Starry: 1^st -2^nd -3^rd - 4^th and 5^th are all ordinal numbers.

f-i-r-s-t ->1^st

s-e-c-o-n-d -> 2^nd

t-h-i-r-d -> 3^rd

f-o-u-r-t-h -> 4^th

f-i-f-t-h -> 5^th

Now here are 10 balloons in the line, each which a number on it 1-2-3-4-5-6-7-8-9 and 10.

In other, the red balloon is 1^st, the blue 2^nd

the green is 3^rd , the  yellow is 4^th, orange is 5^th, purple is 6^th, pink is 7^th , the red and white balloon is 8^th, the balloon with spots is 9^th ,

and the striped balloon is 10^th .

So now we have:

s-i-x-t-h -> 6^th

s-e-v-e-n -> 7^th

e-i-g-h-t-h -> 8^th

n-i-n-e-t-h -> 9^th

And 10^th balloon.

Look at the calendar Starry!

And sure you have learned that there are 7 days in a week.

Now, Monday is the 1^st day of the week.

Tuesday is the 2^nd. Wednesday is the 3^rd.

Thursday is the 4^th day of the week. Friday is the 5^th day.

Saturday is the 6^th day. And Sunday is the last day of the week.

It’s also the 7^th day of the week.

Now, Starry! Let’s do an activity together.

Look at the calendar and fill in the blanks.

Thursday is the (dash) day of the week ? -> 4^th day.

Tuesday comes before (dash) ? -> Wednesday.

Monday is the (dash) day of the week ? -> 1^st day.

Wednesday is the (dash) day of the week ? -> 3^rd day.

The 5^rd day of the week is (dash) ? -> Friday.

The last day of the week, Sunday is also the (dash) day of the week ->7^th day.

The day between Tuesday and Thursday is (dash) day ? -> Wednesday.

Saturday is the (dash) day of the week -> 6^th day.

And now Starry, an activity with the balloons.

Look at the balloons and fill in the blanks.

The 3^rd balloon is (dash) in color ? -> green.

The red and white balloon is the (dash) balloon ? -> 8^th.

The 1^st balloon is (dash) in color ? -> red.

The striped balloon is the (dash) balloon ? -> 10^th.

The orange balloon is the (dash) balloon ->5^th.

The pink balloon is the (dash) balloon ? -> 7^th.

Starry, the next time you get your report card, remember you can’t come 2 in class.

You can be 2^nd. 2 is a cardinal number. 2^nd is the ordinal number
