Growing Geometry Gizmo Lesson Materials
Geometry is the branch of mathematics concerned with points, lines, angles, shapes, and solids. Without a true understanding of the properties and relationships of these figures, students are likely to struggle as they progress toward higher math courses. Gizmos are such a great fit when building students' understanding of geometry because they provide an interactive, inquiry-based experience that reinforces the conceptual understanding students need.
The ExploreLearning team is constantly working to keep your Gizmo resources updated, and we are pleased to share these math Gizmos have all new Lesson Materials.
As always, our goal is real student understanding, beyond just formulas or memorization. For example, in the new Student Exploration Sheets with the Rotations, Reflections, and Translations Gizmo, we work to help students see that each type of transformation is really just a specific rule – a function, essentially – which can be applied to any figure, point by point, to create the transformed figure. In the Mathematical Background, found in the Teacher Guide, we expand on this “transformations as functions” idea, to help support teachers in how they might want to present this topic.
Reminder: Our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)
