Group Activity Cards
Use groups of 3.
Materials: 2 number cubes labeled 1 through 6, grid paper

Creating Triangles 
Label one of the number cubes as the 10's place and the other cube as the 1's place. Everyone should have a sheet of grid paper. Begin by rolling the number cubes to find a value. For example, a roll of 3 on the 10's place cube and a roll of 6 on the 1's place cube would be 36. Let this be the area of your triangle. Each player must then secretly draw a triangle on their grid paper with an area of 36 square units. Label the area, the base and the height of the triangle on the drawing.
When all players are done, compare drawings. Each player should check the other players' drawings to make sure the area is equal to 36. Drawing a triangle with the correct area is worth three points. Drawing a triangle of correct area that is also different from other group member's triangle is worth 3 points.
Continue by taking turns rolling the cubes. Play several rounds. The player with the most points accumulated is the winner.
