Ben Ten Form (Not)


As we continue on with our decimal unit, we come across an interesting fact. There are many ways to write numbers.

We are going to focus on three:




Here is an example of a written number using each method:


Standard form is just how it sounds. Standard. This is how we usually write numbers when solving math problems. Pretty standard stuff.

We can also write a number out in words. When doing this, it helps to say the number aloud. Then write what you hear. If there is a decimal, you write "and." That's the only time "and" should be in the written form of the number.

This video will help explain how to read a number that includes a decimal.

Next up is Base-10 Form.

Base-10 numbers are written as products added together. Use place values to help you. Imagine collecting base-ten blocks to show the value of the number. Essentially, that's how this form breaks down.

Here's a comparison:

Now you're getting the hang of it.
