Check the comparison reason

Read the whole source. Pick one way to make your guide. You can point, speak, sign, use AAC, draw, build or ask someone to write your exact words. Stop for a break whenever you need one.

Fictional quantity card set: Which place has the six? First card states 460 labels; second card states 406 labels; third card states 604 labels. These are stated counts of the same kind of label, not observed stocks, money, distances or prices. A helper claims 406 is more than 460 because the last digit 6 is larger than 0. Decide whether that reason supports the actual quantities. The task is to represent, compare or order these stated quantities and give a checking reason.
Make a useful quantity guide. Keep the whole quantity and the value of each digit clear.
