Introduction

The Nemeth Focused Lessons are designed to help students learn the Nemeth symbols and increase their knowledge and understanding of key mathematical concepts. Students of any age may enjoy and learn from the lessons, especially if they need a refresher or additional practice with Nemeth symbols.

The focused lessons were developed in response to feedback from dozens of students interested in learning new Nemeth symbols in a fun and supportive way. The user-friendly focused lessons include:

• How to read and write new symbols in Nemeth Code
• How to use these symbols for math concepts and applications like number lines and modified expressions
• Examples in braille
• Examples in print for parents and teachers
• Activities and games to reinforce the new symbols
• List of special symbols for reference
• Abbreviated lesson documents with only examples and problems for students who are transitioning to braille or new to the Nemeth Code
• Teacher Guide
