Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties through an easy-to-use interface.
Students explore geometry using a Rubik's Cube. In this 2-D and 3-D shapes lesson plan, students use the Rubik's Cube to find the center, edge and corner pieces. Students then find the dimensions of the Rubik's Cube and read the solution guide. After reading students demonstrate methods and algorithms.
How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the angles in a triangle. Resource links are included.
Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are not only a part of America's heritage, and relate it to math and geometry. Students are introduced to a variety of geometric figures during a unit of geometry.
Origami is an excellent way to combine Japanese culture, art, and geometric shapes into one engaging lesson plan! Scholars begin by listening to the story Sadako and the Thousand Paper Cranes and learn the origin of the word origami, geometry, and symmetry. Learners watch a short intstructional video depicting a simple origami project and locate shapes they recognize. Next, they practice origami themselves using the intructional prompts. Consider doing this yourself on a document camera, or having an experienced artist come speak to the kids about this practice. As learners fold, they pay attention to familiar shapes. There is a worksheet to solidify geometric concepts, and the lesson plan suggests taking pictures of the origami stages to create a PhotoStory presentation.
The University of New York Regents High School Exam for geometry from August 2009 is comprehensive in scope with 38 questions over 22 pages. Geometers can assess their mastery of core content with a combination of multiple choice and constructed response questions. A reference sheet with relevant formulas is included.
Young scholars explore the concept of geometry. In this geometry instructional activity, students practice problems from the geometry regents exam. Young scholars answer practice problems that are multiple choice. Students answer questions involving angle measures, parallel lines, shapes, congruent figures, circles, perpendicular lines, etc.
Young scholars practice the high school Regents exam. In this high school regents exam lesson, students practice geometry sample problems from a past Regents exam. Young scholars solve problems involving angle measures, side lengths, parallel and perpendicular lines, Pythagorean theorem, and other geometry topics.
Here is a clever, cross-curricular lesson that combines art and geometry. Learners design a painting that uses geometrical shapes and is symmetrical. Sponge-shaped geometrical figures are used to design half a page and fold them to create the other half. Everyone displays their pictures of geometry and symmetry.
