What's this number? [Math, Classroom]

I've been working through this worksheet with my 3rd - 5th Math Enrichment kids as a way to teach them about prime numbers, squares, square roots, identity properties, and more.  Piggytailing off my last post about homework, I'd like to clarify that I only let the 5th graders even take this sheet out of the room.  The 3rd and 4th graders leave their sheets with me until we're together again.  This sheet really is just a springboard to learn about Math terminology.  The 5th graders are advanced enough that they work in groups to figure them out themselves.

I've published the Google Doc so feel free to use it.  On the doc is a link to the site where I got my info.  What's Special About This Number? has info on almost every number from 0-9999.  I found that original site from FreeTech4Teachers.com. Click the picture to see the doc.
