What you may do
- Use the method in class: students write each problem in one line on the notebook page. How Tiaotiao learns →
- Print or photocopy the study sheets for any students at your school. Charging only the cost of the copies is fine.
- Upload the PDFs to your class on Google Classroom, Microsoft Teams or a WhatsApp group.
- Send the lesson links to your students, and share them with other teachers.
- Change them for your class, for example add notes or leave out questions, as long as the Tiaotiao name and website stay on the page.
Please do not sell them, put them behind a paywall, or remove the Tiaotiao name.
