What This Standard Means
What Students Need to Do
- Students learn about people from other countries who developed useful ideas in the past. They explain how those ideas still help people today.
What Mastery Looks Like
- A student can explain that Louis Braille, from France, created raised-dot writing that many blind people read. They can also explain that Marie Curie, born in Poland, helped bring X-ray machines to injured people, and doctors still use X-rays.
Common Misconceptions
- Students may think Braille is a language rather than a way to read and write with raised dots. They may also think Marie Curie invented X-rays, rather than helping make them available to injured people.
How to Assess It
- Give students pictures of a braille elevator label and a mobile X-ray machine. Ask them to match each picture to Louis Braille or Marie Curie and write how it helps people today.

Ways to Teach It
Give students foam dots and a braille alphabet chart, then have them make the first letter of their name.
Ask: How could raised dots help someone read a sign if they cannot see the printed words?
Have pairs match picture cards showing Braille and Curie's mobile X-ray units with cards showing how each helped people.
Show a photo of braille beside an elevator button and ask students how the label helps someone choose a floor.
