Jewel River

Even the youngest children have the ability to tell the difference between clusters of one, two, three, and four. Jewel River lets kids practice this knowledge in a game that's designed for two kids to play together unsupervised, such as in a preschool classroom or daycare setting. Playing together encourages kids to talk with each other about what they're doing, which can deepen the learning experience.

Jewel River is no longer available, but here is a video review.
