A standard number is a "regular number" such as 5978 or 154278963152.

Standard Form: 123

Expanded Form: 100 + 20 + 3

Written Form: one hundred twenty-three

Tips:

Furthermore, if you have a hard time remembering this, think of it as this way:

The standard form is normal. Standard means the original number.

The expanded form means the largest way. Expand means to make something big.

The written form is writing the number down in words. Written reminds me of language arts. So convert the "math number" into a "language art number".
