Also called the "attribute" or "classification" train. A fun activity/game for young learners. The idea is simple enough. Start a train with an item, or shape. It doesn't have to be mathematical, though that is a good place to start. The second item, the next carriage, should share a quality, an attribute, with the first part of the train. So for example, if your first part, the engine, is a yellow triangle, the next person could choose another triangle, something yellow, something pointy etc.
