What teachers get
You can see inside every lesson.
The lens
"See how it's built" opens the branch map, the standards each lesson targets and the misconceptions it is aimed at.
How a student got there
The lens keeps a log of every move, so you can see the path a student took. The log stays in that student's own browser.
Standards named
Algebra 1 is mapped to the Virginia 2023 standards, and the pre-algebra samples to Common Core.
A teacher file
Echo's capstone ends in a portfolio and a teacher file that you can score on your own device, with no server involved.
Privacy by design
No student accounts, and no personal data collected. Progress is saved on the student's device. Read the safety page.
Age-aware AI
Echo's live chatbot is for students 13 and up. Younger students use the on-their-own route.
