Teaching Expanded and Standard Form
What it is
Expanded form writes a number as the sum of its place values (300 + 40 + 2); standard form is the usual way (342).
When a child is ready
Teach it once hundreds, tens, and ones are understood.
If they struggle
Use a place-value chart and write each digit in its column before writing the expanded form. Zeros are the usual trouble spot: 305 is 300 + 5, with no tens.
