The Tutorial: Google Classroom in School was developed within the project eSGarden – School Gardens for Future Citizens ( 2019-2022 | 2018-1-ES01-KA201-050599). Considering that since COVID-19, schools have been working with online educational resources to communicate with teachers and students, organize work, submit documents, complete assignments and assessments, etc., this tutorial explains the notions that every teacher must know to take advantage of the Google Suite platform.
