This depends on the age and curriculum of the student.
For younger students we use a combination of hands-on activities, worksheets, interactive notebooks as well as games, flashcards and other resources.
For Middle School and High School students we use a combination of the student's own textbook as well as additional supplementary worksheets or exercises which we provide.
For IB students we have access to official IB databases which allows us to retrieve a variety of IB material to help students accordingly.
