Desmos helps you understand, not just finish.
Can You Use Desmos on Your Phone?
Yes. You can use Desmos on a phone. But a bigger screen is better. A Chromebook or laptop gives you more room. It’s easier to type and see graphs that way.
Use what you have. If you use a phone, turn it sideways to see more.
What If You Leave the Activity?
Desmos saves your work. You don’t need to click “save.” If you close the tab, your answers stay there. Just return to the same place using the same login or browser.
Ask your teacher if you are not sure. They may have set rules for saving or finishing work.
Can Your Teacher See Your Answers?
Yes. Your teacher can see your work as you do it. They see what you type. They see how you move things on graphs. If you get stuck, they can help. They may also share answers with the class, but they can hide your name.
Your classmates can’t see your answers unless your teacher shows them to the class.

Can You Work at Your Own Speed?
Sometimes. Your teacher may let you go slide by slide at your own speed. Or they may move the whole class together. If you finish early, you can look back and fix answers.
Ask your teacher how the lesson will work that day.
What If You’re Stuck?
Tell your teacher. They can send you a note in Desmos or help you in person. You can also go back to other slides and try again. Sometimes just reading the question again helps.
Don’t wait too long if you’re confused. Ask for help.
