Dam Jammer Geometry Shape Game

Dam Jammer is an arcade style game that focuses on shape recognition, applying geometric transformations, and the relationships of shapes.

Dam Jammer has three levels.  In the first two levels, holes in the dam are in the form of basic shapes. In Level 1, players match basic shapes to the holes.  As each shape is placed, its name is displayed and spoken.  Level 2 requires players to flip and turn shapes to make them match the holes.  In Level 3, players have to fill in square or rectangular spaces by putting together several shapes.

Preschoolers to children in early elementary grades will enjoy learning about shapes in this engaging activity!  Progress can be tracked with scores and by the number of rounds that are completed.
