Attribute pieces are used in games and activities for sorting and classifying, reasoning logically, formulating and verifying hypotheses, and developing an understanding the mathematical meaning of "or," "and," and "not" using Venn diagrams. Just for Fun: Attribute Identity Game

The slope of lines and line segments as rise over run and the slope intercept form of a linear equation are introduced through modeling line segments on geoboards or geoboard recording paper. These ideas are then used to explore parallel lines, perpendicular lines and other families of lines. Just for Fun: Coordinate Guessing & Hide a Region

Students work in groups to solve logic problems. Clues for a problem are distributed among the members of the group who then must work cooperatively to solve the problem. Just for Fun: Pica-Centro
