Day 2: 24/9/2013- Whole Numbers

 

Today in class, I learn about numbers. So what are whole numbers?

Whole number are a collection of positive numbers and zero. The whole number is represented as {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ….}.

Whole numbers can be used as:

Cardinal Numbers: Tells “how many.” Cardinal numbers are also known as “counting numbers,” because they show quantity.

Ordinal Numbers: Tell the order of things in a set—first, second, third, etc. Ordinal numbers do not show quantity. They only show time or space.

Nominal numbers:  Names something—a telephone number, a player on a team. Nominal numbers do not show quantity or rank. They are used only to identify something.

I find an interesting video about Number bonds by Dr. Yeap Ban Har and will like to share with everyone:
