Welcome to the Nemeth Braille Code Curriculum!
Proficiency in Nemeth Code is essential for accessing grade-level mathematics and science materials for K-16 students who are blind or low vision and read braille. The curriculum and database have been developed by Pearson's Accessibility Team for Assessments to increase proficiency of the Nemeth Code and reinforce grade-level mathematics concepts for students who are visually impaired. The project manager was Corey Fauble, and the curriculum team included: Dr. Tina Herzberg, Susan Osterhaus, Sara Larkin, and Carolyn Mason.
The authors wish to thank the:
- American Printing House for the Blind for allowing us to reference their products and include information about how the various products could be used with the curriculum.
- Members of the Maryland Braille Task Force for Mathematics including Susan Adams, Dr. Michael J. Bina, Eldre Boggs, Melinda Demaris, Karen Ehrhardt Lloyd, Heather Johnson, Dr. Allison Layland, Jacqueline Otwell, Susan Polansky, Melissa Riccobono, Jill Richmond, Dr. Karen Ross, Carol Seckington, Sally Shreck, Linda Starner, and Lisa Wright. Their work on the Maryland Common Core State Curriculum Frameworks for Braille: Mathematics assisted us in aligning the Nemeth symbols by grade-level and served as a great resource as we have developed the curriculum!
- Members of the National Federation of the Blind, for their valuable feedback and recommendations about the Nemeth Braille Curriculum, Nemeth Braille Searchable Database, and the Nemeth Braille Code Focused Lessons during user studies. We also appreciate NFB's assistance in recruiting individuals to participate in user studies at their annual conventions from 2016 - 2018. Texas School for the Blind and Visually Impaired for their permission to use the Commonly Used Nemeth Mathematics Symbols Arranged by Grade and Course chart from the Texas School for the Blind and Visually Impaired publication “Nemeth at a Glance”.
- The authors also wish to thank the following companies:
- Didax, Inc. the maker/distributor of Omnifix, Geostix, and other math products for allowing us to reference their products and how they can be used with the curriculum. Omnifix and Geostix materials with their tactile properties make them especially useful with students who are blind or low vision. Their teddy bear counters are good for developing beginning number concepts.
- E.A.S.Y. LLC for allowing us to reference their interactive tactile graphics products and include information about how they can be used with the curriculum. They provided inTACT Sketchpads and materials for the authors' use when developing activities that incorporate tactile drawings. E.A.S.Y. shares our conviction that drawing is an essential part of tactile literacy for blind and low-vision students.
- Omnicor, Inc. the maker of Wikki Stix® and the Wikki Stix® STEM Pak for Math and Science for allowing us to reference their product and how they can be used with the curriculum. Wikki Stix® are especially useful when creating math tactile graphics or just fun tactile pictures.
- Uncle Goose for allowing us to reference their products and include information about how their products could be used with the curriculum. Their braille math blocks are a fun way to introduce and reinforce Nemeth braille numbers and math symbols.
- Wolf Products, Inc. the maker of the Math Window for allowing us to reference their products and how they can be used with the curriculum. The Math Window is an easy-to-use math teaching tool for blind and visually impaired students. Math problems area easily built, and changed as needed, using this movable Braille method.
