1. Preparing to Read

Build Knowledge and Vocabulary 

Before reading the article, create an enlarged KWL chart on a whiteboard or chart paper. Invite students to share what they know about braille (K column), what they wonder about braille (W column), and after reading the article, one to two facts they learned (L column). Then use the Skill Builder Words to Know to preteach domain-specific terms. 

2. Reading and Discussing

Read the Article

Read the article aloud or have students read it independently or in pairs. As students read, direct them to circle or highlight any words whose meanings they’re unsure of. 

Answer Close-Reading Questions

Have students write their responses, or use the Close-Reading Questions to guide a discussion.

• How did Louis Braille’s education influence his success as an inventor? (Skill: Summarizing)
After going blind, Louis was encouraged by his family to continue learning and to be as independent as possible. He became one of the best students at school and earned a scholarship to a school for blind students. There, Louis was challenged by the existing ways of reading and writing for the blind. He was inspired to improve the methods blind people could use to read and write. Without his dedication to learning, Louis might never have invented braille, which so many people rely on today. 

• What is the purpose of the section titled “Night Writing”? (Skill: Author’s Purpose)
The purpose of the section “Night Writing” is to explain the details of a language system that inspired Louis to create braille. Developed by Charles Barbier, “night writing” used raised dots to represent letters or sounds and help soldiers read messages in the dark. Louis eventually improved Barbier’s system and created braille. 

• Why is braille considered “one of the world’s greatest inventions”? Support your response with evidence from the text. (Skill: Cite Text Evidence) 
Braille is considered “one of the world’s greatest inventions” because of its impact on the world. The text states, “The raised-dot system is everywhere—in museums and offices and on elevator buttons, ATMs, and more.” 

3. Skill Building

Analyze a Primary Source 

Direct students to the “Your Turn” activity at the end of the article. Provide this question to consider as they analyze the quote: How does access to communication provide access to knowledge and equality? Then assign the primary source Skill Builder A Tribute to Louis Braille and ask: How does Helen Keller support Louis Braille’s statement?
