Well, we've been using these for about a month, now and they're working GREAT! I first told you about this terrific free resource here. Dd#2 is doing so well, that she's moving down the list on the back of the cards to memorize new information about each state. It's been an easy thing for her to add to her school and I just test her at the end of each week with the cards to see what she's learned from them! I'm soo pleased with them and they're holding up great pasting them front and back to a larger piece of cardstock and laminating them. The kid that designed these did a fantastic job!!
