1. Use Google Classroom
It can be your best friend to set-up your work using this wonderful tool along with Google Drive and its productivity apps like Docs, Slides, and Sheet, etc.
2. Snagit by TechSmith
You can easily screencast your directions using this wonderful and FREE extension! For example, students are starting a unit using Scratch and need to make an account. If you want to splurge, Camtasia by TechSmith is a wonderful screencasting and editing tool. I purchased mine on sale! I made this video for my students:
3. When in Doubt, Try a Hyperdoc
I have been trying different methods and ways to deliver content and lessons to students and if you have a few links for students to use, make a hyperdoc! Yes, it is more set-up, but my students love working at their own pace and absent students can easily complete the work too! Don't forget to post in Google Classroom! You can look at my example by selecting this LINK. Yes, I number my assignments for Google Classroom. For more information, read this blog by Alice Keeler.
4. Change Your Share Settings
Lastly, change your share settings on all the items in your Google Drive to "Anyone with the Link" can view. Copy the links and add them to your sub/guest teacher plans. This allows your guest teacher to look over the work easily! I personally use PlanbookEDU for my online lesson plan book. There are many different tools you can use for this, but this is the tool. You can add your standards to your lessons and easily organize and move lessons around. I have used for a few years now and really like it. PlanbookEDU lets you create a PDF of your lesson plan for the day. Just perfect for guest teachers!
5. Create a Google Form for Guest Teacher Feedback
Why not create a form for guest teachers to complete? Change the settings so that anyone can complete and leave a link for the guest teacher to access!
Try one or all of these tips and hopefully, it will help you stay cool and calm when you have to call in next time!
