Ordering Decimals

To order decimals, students need to understand the relative size of the digits.  I’ve found that even students who understand decimals conceptually tend to resort to incorrect techniques when ordering decimals.

Ordering Mat

This sheet has students represent 4 decimal numbers in each corner of the mat using a placed value chart and a visual representation before ordering them.  It basically reminds them to use ideas of the size of the digits.
