### Decimal Place Value

August is already here! Lazy mornings of summer holidays are just flying by and a new school year is starting soon. I will miss the summer fun, but I am more than ready to start another thrilling academic year with new goals, new challenges, and a hope to make this the best school year ever!

While thinking of upper elementary math, the first topic that comes to my mind is a refresher on the number place value system. These young minds already know the whole number place value, but it’s good to refresh the same and introduce the decimal place value too.

The origin of the Arabic number system that we use today can be traced back to the Hindu Scholars in India. This system was adopted and modified by Middle Eastern Scholars and later introduced in Europe. Without going into too much history, let's look at the place value system.

The set of 10 symbols namely 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 represent the numbers.

In the place value system, the position of the number defines the value of the number.

For example, if I write the number 786 then:

• 6 in 786 means 6 ones or 6
• 8 in 786 means 8 tens or 80
• 7 in 786 means 7 hundreds or 700

Now for decimals, the place value system extends to the right of ones place to represent the fractions.

For example, if I write the number 786.432 then:
• 4 in 786.432 means 4 tenths or 0.4
• 3 in 786.432 means 3 hundredths or .03
• 2 in 786.432 means 2 thousandths or .002

### Odd and Even numbers

Even numbers: Even numbers are the numbers that are divisible by 2. For example, 8 can be divided by 2, so 8 is an even number.

Odd numbers: Odd numbers are the numbers that are not divisible by 2. For example, 9 cannot be divided by 2, so 9 is an odd number.

This definition works well with the kids who are familiar with multiplication and division. As this concept is introduced to first graders or second graders where a majority of kids are not familiar with Multiplication and Division, so we should teach this in a different way.

Even numbers: A number is even if it can be divided into groups of 2 and have no leftovers. For example, 8 can be divided into 4 groups of 2 and there is no leftover, so 8 is an even number.

Odd numbers: A number is odd if it can be divided into groups of 2 and have 1 leftover. For example, when dividing 9 into groups of 2 we can make 4 groups of 2 and there is still 1 leftover, so 9 is an odd number.

• An even number ends in 0, 2, 4, 6, or 8.
• An odd number ends in 1, 3, 5, 7, or 9.

For example, 239 is an odd number as it has 9 at ones place. Similarly, 238 is even number as it has 8 at ones place.
