# Geometry Resources for Students with Visual Impairment

## Geometry materials and activity ideas for teaching students who are blind or visually impaired

Teachers often wonder what instructional materials are available to teach geometry to students who are blind or visually impaired.  These are some of my favorite resources.  Some are teacher-made and some are commercially available. (Editor’s note:  The author is British, so many of these suppliers are in the UK.  Similar products are available in the United States and Canada.)

### 2D and 3D Shapes Resources
