1. Making and Verifying Conjectures about Angles

    • Resource ID: GM1L7
    • Grade Range: 9–12
    • Subject: Math

    Given the relationship(s) among a set of angles, the student investigates the patterns and makes conjectures about the geometric relationships, including angles formed by parallel lines cut by a transversal.

  2. Determining Area: Sectors of Circles

    • Resource ID: GM4L3
    • Grade Range: 9–12
    • Subject: Math

    Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.

  3. Graphing Conic Sections: Ellipses

    • Resource ID: PCM1L2
    • Grade Range: 9–12
    • Subject: Math

    Given an equation, the student will use parameter changes to graph an ellipse and to identify the changes in the graph of an ellipse.

  4. Graphing Conic Sections: Hyperbolas

    • Resource ID: PCM1L3
    • Grade Range: 9–12
    • Subject: Math

    Given an equation, the student will use parameter changes to graph a hyperbola and to identify the changes in the graph of a hyperbola.
