The most important step is for students to grab and drag a vertex of the triangle, and observe how that changes the measurements of the figure, which dynamically update as the vertex is dragged. The other relationships within special right triangles are developed as well. Students should notice that the length of the short leg is half the hypotenuse in at 30°–60°–90° triangle, and this doesn’t change even as the triangle changes size. During the activity, ask questions to spur understanding: What do you notice? What changes and what stays the same? What if we try this or that? What else do you want to measure? Special Right Triangles :
All of the handouts are provided in Word format so you can edit them for your students and your class objectives.Īn “invariant” is a measurement or location that doesn’t change even when the figure is manipulated and moved, such as the sum of the interior angles of a triangle. The accompanying paper handout asks students targeted questions to focus their learning. On this screen, moving point D off the circle, on the circle, or to the center of the circle highlights the relationships. Students interact with points on a circle to learn the distinction between major and minor arcs and their relationship to central angles and inscribed angles. As each formula is developed in this TI-Nspire document, we have productive discussions in my classroom: Why does it work? Can you explain it another way? After changing the base and height of the rectangle as desired, they manipulate the parallelogram to notice that the areas are the same. In this activity, students explore the relationships among area formulas for parallelograms, rectangles, triangles, and trapezoids. To grab an available object, swipe on the Touchpad to move the cursor into place and then press ctrl then click (center of the touchpad) for the “grabber hand.” Pay attention to the cursor’s appearance and any messages that appear to be sure you have selected the desired object.

Students do not need to be expert users of TI-Nspire to work successfully with these ready-made documents in many cases, knowing how to grab and drag a slider or object is sufficient. Dynamic geometry software, such as the TI-Nspire geometry app, allows for motion that clarifies properties for students. Many geometric concepts are difficult to visualize, especially in a static paper-and-pencil environment. Read on for some ways I use TI-Nspire in my Geometry class. This power gets combined with linked multiple representations on TI-Nspire CX handhelds and software, enabling students to make rich mathematical connections in Geometry.
