The first-grade children explored attribute rules and games this week. Students first identified the shapes of their blocks; triangle, square, rectangle, hexagon, or circle. These shapes can be organized further by identifying the size and color. A game that was played by all three classes is called The Attribute Train Game. This is a whole class activity with all children taking turns to build a line of blocks on the floor, by following attribute rules. The train begins with one block placed in the center of the playing area. Then each child chooses a block that is different in only one way- shape, size, or color from the first block. There was also an expectation of each child to explain their thinking. In this game, play continues until everyone has had a turn. Variations of the game to challenge thinking include; placing a block down that is the same in two ways, or placing a block down that doesn’t share an attribute with the one in play.
