These activities have been created to allow you to put into practice the skills listed under each skill level. The only way to become proficient in the use of Google is to actually put it into regular use.
Create a new Google Site for you to use with your students. Include relevant content on the site about your class (class rules, syllabus, links to important information). When you are finished, publish the site and copy the link to the published site. Add this link in your Google Classroom as "Materials" (directions can be found in Google Classroom Level 1). Use this site as a way to provide relevant content to students that they can easily access by using the link you provided to them in Google Classroom.
Assign your students to make a Google site as a means of demonstrating what they have learned from a recent unit.
Have your students create a Google Site to demonstrate what they have learned from a recent unit of study in your class. Feel free to provide them with links to the three levels of Google Sites training to assist them if they are unfamiliar with how to create and publish Google Sites. Have them turn in the final published link to you via an assignment in Google Classroom.
