Technical notes

• Students need to be signed into their own account in order to save their work in the lesson. Students 13 or older can create their own registration. Parents or teachers of students younger than 13 can create an account for them. (Provide the adult's email address.) We don't recommend that students sign into a teacher's account because it gives them administrative powers over that teacher's folders.
• Students must save each screen of the lesson before moving on to the next screen. Once they have saved a screen, they cannot go back to change their work. Saved work can be printed and submitted to the teacher as a formative assessment. Final assignments must be written outside of the lesson and submitted separately.
• Students must save their answers to any multiple-choice questions before moving on to the next screen or their work will not be saved.
• Students are able to start over or repeat a lesson. If they do, their saved work will be deleted and a new record will be started.
