debbie oestreicher's List: Math - Geometry

Interactives Geometry 3D Shapes is a great website for students to learn about 3D shapes, surface area and volume, Euler’s theorem, and platonic solids. Each section gives students an interactive environment where they can manipulate 3D objects as they learn. In the surface and area section, students can learn how to calculate area of a 3D object and then have an interactive space to practice calculating the area of 3D objects. At the end of the site there is a place where students can put their knowledge to the test and apply what they have learned. This is an outstanding alternative to learning from a text book. The Interactives site gives students what a text book can’t, interaction with 3D shapes and the ability to rotate and manipulate the shapes.

This unit teaches geometry through the use of geoboards, grid paper, tracing paper, origami, objects in the home, and the grocery store to bring an understanding to students that geometry is a part of their lives.
