Thanks to Teacher Tipster, I made a run to Dollar Tree. They had the condiment trays featured in the video that Mary at Guided Math shared. http://www.youtube.com/user/teachertipster?feature=mhum#p/u/18/0ch4fTFFgcs
My dice are still at school. I bought 2 trays so that I can still use one in small group and have one at a station. I'm so glad that I have such awesome Blog Buddies!
