Graphing Coordinates
Sixth graders practice graphing coordinates. For this geometry lesson, they use the x and y axis to locate points that must be connected in the right sequence to form a straight line.
Curated OER
Polygon Quilt
Learners participate in a game with different types of polygons. They use triangles to create as many polygons as possible. They also review their colors by having different polygons be a different color.
Curated OER
Probability: The Study of Chance
Learners practice the basic principles of probability by conducting an experiment, determining if a game is fair, collecting data, interpreting data, displaying data, conducting analysis, and stating and applying the rule for probability.
