The Tray Game. My son really likes this game. When we first started playing back in January it was a little bit of a struggle and he would be wrong or not know about half the time. Now I can remove 3 objects at once. He just turned 4 in May so he tells me what objects are missing instead of writing them down. We've worked up to using themes some times. For example instead of using very different objects we'll use all toy cars.
