Give the correct number for each set of objects.

What are the things that you use in school?

What do you usually use in writing?

If your classmate came to school without pencil, and you still have an extra pencil, will you share it with him? Why?

A store owner bundled the remaining pencils into 10. He made 10 bundles of 10 pencils? How many pencils was the store owner bundled in all?

What did the store owner do?

How many bundles of pencils did he bundle?

How many pencils are there in each bundle?

How many pencils do we have in all?

100100

If we will put together 10 bundles of 10 pencils, how many pencils do we have in all?

101101

What if I add one pencil, how many pencils do we have?

So there are “one hundred one” pencils.

102102

What if I add another pencil,

There would be “one hundred two” pencils.

How many pencils do you have now?

103103

What if I add another pencil,

There would be “one hundred two” pencils.

How many pencils do we have now?

Let us read your answers and try to figure out what

number comes next:

101, 102, 103, , ,

106, , ,109, 110

What happens to the number ?

how many straws do we have?

Now, let us try another example. Let say we have two bundles of 100 straws:
