It's great to have a nice collection of go-to games that work well for your class. As you know, each class has different dynamics, so what will work for one class might not work for another. Most of these games I have here are for the younger kiddos, but some can adapted for the older Foundations crowd. Take a look!
Brandy at Half-a-Hundred Acre Wood has a great review game link-up if you're looking for more ideas!
