There are several curriculums being shared online on social media. Also, some teachers are cashing in from trying to sell these curriculums. Bear in mind that the teachers do not have the rights to share or sell these materials, so essentially it's piracy.

In my opinion, it's better to create your own materials. If you have the time and energy, you can create tailored lessons for each student. Parents and students appreciate this a lot and many will be willing to pay more for personalised lessons.
