Comparing numbers

Let us compare the single digit number with two digit number for example., 9 and 15

15 is greater than 9

While comparing single digit numbers with two digit numbers, we see that two digit number is always greater than the single digit number.

1. Let us compare the two digit numbers with different tens 25 and 35

It is enough to compare tens place of the two given numbers. There are 2 tens in 25.  3 tens in 35.

2 tens is less than 3 tens.

So, 25 is less than 35.

35 is greater than 25.

2. Let us compare the two digit numbers with different ones 27 and 24

Here the tens places are equal. Then we have to compare the ones.

There are 7 ones in 27.

4 ones in 24.

7 ones is greater than 4 ones.

So, 27 is greater than 24.

24 is less than 27.

Teacher Note: Teacher should insist that while comparing  two digit numbers with different  tens place children can compare only tens place . If the tens place are the same, they need to compare the ones place.
