Map Work Idea

I have this idea from Dianne in Texas...
She uses:
http://www.worksheetworks.com/
Here you can print out a map with labels and also a blank one.
She says:
Right now, we are doing the oceans. I have one world map printed out that labels the oceans only and one map that is blank. I just have them copy the oceans on their blank map by looking at the labeled map. We do that once a week. After a few weeks, I will take away the labeled map and they will have to fill out their blank map from memory. I will continue this with continents, states, countries, etc. and build on what they've already done. So, hopefully, one day they will know the world map from memory!
