The student version of the presentation contains multiple blanks that need to be filled in throughout the lesson. These blanks are conveniently underlined and bolded on the teacher copy.

Google and Distance Learning Ready

• This lesson includes both Office and Google formats for ALL resources. The presentation is in PowerPoint and Google Slides while all documents contain Word and Google Doc versions.
• Your resource is perfect for distance learning and integrates seamlessly with Google Classroom as I've included a link that will automatically create a copy of the resources and put them directly into your Google Drive with one click.
• Purchase --> Open --> Click --> Assign to your students

Having both options allows you to use either without worrying about formatting issues as all the work has already been done for you. It safeguards you in case your department or school decides to go Google 100% and allows you as well as your students to access everything no matter where you are or what kind of equipment is being used.

Exit Ticket

Included in your package is an Exit Ticket which can be directly accessed from the last Google Slide. Additionally, your purchase will create a copy of the Google Form Exit Ticket which you can edit to meet your class needs.
