If you are reading this, you are probably trying to check if your district allows access to Google Sites™. You should test this link on a teacher's computer/account as well as a student's computer/account. Sometimes teachers are not blocked from the Google Sites™ , but students are.
I have put some features below that are common on some of my Google Sites™. Play around with each feature and see if you and your students will be able to access them on your district's network. You should see the following items below...
A picture of a lemon
An embedded Google Form™ that you can answer and submit
A puzzle of a palm tree that you can complete
A video of 'elephant toothpaste' that you can play
If your student's cannot access this site, you may be able to reach out to your technology facilitator at your school to see if there is a setting they are able to adjust to allow students access. If they cannot change the setting to allow access to your students you should NOT buy the product a your students will be unable to access it in on your districts network.
