#1) http://www.emints.org/ethemes/resources/S00001385.shtml shared by Garrett — has many excellent links including some of our runners-up…a great resource!

The runners-up:
#2) http://www.aaamath.com/plc31d-placevalue-add.html shared by Brody, Abby, and Tylan — has a good description of place value and expanded form, along with an interactive practice game.
#3) http://www.studyzone.org/testprep/math4/d/hp/standard.htm shared by John, William, and Chase — has an interactive practice game for expanded form.
#4) http://www.icoachmath.com/SiteMap/ExpandedForm.html shared by Ellie, Sadie, Allison, Amanda, Charley, and Kelsie — has an excellent description of standard and expanded forms, but some students seemed to be getting a message that this site may require you to install extra software to view it correctly?
#5) http://mathcentral.uregina.ca/QQ/database/QQ.09.07/h/kent1.html shared by Alex, Ryan, John, Tyler, Carissa, Alex, Molly, Tyler, Dylan, Allison, Amanda, Kenzi, Kaitlynn, Charley, and Kelsie — a very popular site and one of the only ones in this list to explain expanded exponential form!
#6) http://mathforum.org/library/drmath/view/57137.html shared by Michael and Molly — another good explanation of standard and expanded forms.
