There is an important distinction between drawing and constructing figures in dynamic geometry environments. Here is a package of files for the Midsegment activity that allows you to scaffold as needed in your class: Midsegment Calculator Files. Transfer the calculator file between calculators with the link menu, or use the free TI-Connect CE software. If your time is short, or you want your students to focus on the concepts and results rather than constructing the figure, use a ready-made figure that you create or download. You can rely on numerical justification or move onto a formal proof if that meets your lesson objectives. Discuss as a class what students noticed and why these properties hold true. 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. The Midsegments of Triangles activity gives students step-by-step directions to construct the figure, and they can investigate several properties that occur.

Sides and angles can be measured, and these values update dynamically as a vertex or a side is grabbed and moved, giving students opportunities to observe and make conjectures about geometric relationships.Īsk questions to spur understanding: What do you notice? What changes and what stays the same? What if we try this or that? When a geometric figure such as a triangle is created in Cabri Jr., it can be dragged and moved to provide students with multiple (infinitely many!) examples of triangles to explore. Pay attention to the cursor’s appearance and what is “flashing” since that is what the cursor will act upon. When no tool is active, move the cursor to an available object and grab it by pressing the alpha button. Use the arrows to move within a menu and around the screen, and press clear to exit a menu or a tool. Press enter to select a menu item and notice that a “tool icon” appears in the upper left corner of the screen indicating which tool is active. The menus F1 through F5 are accessed using the five keys under the screen: y=, window, zoom, trace, and graph. Press the apps button and select Cabri Jr. is available for the entire TI-84+ family).

Here are some suggestions on how to use the Cabri Jr. Lessons using this technology allow students to create their own geometry knowledge and are also more fun than reading properties and theorems out of a textbook. When students interact with dynamic geometry software, they can construct, measure, and move figures to explore properties, confirm theorems, and visualize geometric situations.
