Here are a few web sites:
http://www.mikesfreegifs.com/
this has free animation,
just copy and paste to a message or your own site...
http://usscouts.org/advance/documents.asp
this takes you to a page that has "advancement documents",
but the whole site is a really good source of info...
http://usscouts.org/cubmaster/carrows.asp
same site,
their career arrows are cool
given to webelos 2 at the arrow of light/bridging ceremony...
http://www.animatedknots.com/
Great animated step by step knot tying,
you can actually have this site customize a knot-site for your pack,
and link it to your own pack web site...
http://geocities.com/~pack215/cub-tracker.html
lots of info,
like the requirements and acheivments for the ranks
their excel spreadsheets for advancements are really simple to use...
http://www.ivory.com/PureFun_IvoryProjects_SoapCarvingTips.htm
when your cubs get to bear they will earn their whittl'n chip (pocket knife) card,
Ivory is suppose to be the "best" soap to use,
and Ivory has a page completely devoted to it...
just make sure you unwrap the soap
and leave it out a week prior to your carving,
otherwise the soap sticks to the knife and the soap comes off in chunks...
LOL!!! learned that the hard way :)
http://www.theteacherscorner.net/printable-worksheets/make-your-own/
this site is great too,
you can make your own word search, word scramble, math worksheets, etc...
or you can use one of theirs thats already made,
if we need an opening den activity
we usually try to make one up with the monthly theme,
the boys are disappointed when we don't have one....
http://www.scouting.org/philmont/
