When students write the word form or expanded form of numbers to the hundred thousands, they may
incorrectly express zeros that come in between numbers.
Example: 206,000
Students may incorrectly express 206,000 as two hundreds zero six thousands in word form and
200,000 00,000 6,000 in expanded form.
Show the students that when there is a zero in between other digits, it is not written in the word and
expanded forms as shown in the example below.
