how can we lockdown ipad to only certain pages??

content filter configuration profile - built-in: specific websites only?

Yeah the content filter will get the school webpage portion accomplished. If we're talking about the Google Classroom app (I presume we are) then you can also combine the content filter with a Restriction like so:

So then the only apps that will display on the iPad are Google Classroom, Safari, and the Settings app. (Can't get rid of Settings)

Not sure if restricting apps like this is more heavy-handed than you're going for, but, it'd get the job done. With this workflow combined with @thejenbot's suggestion, they could ONLY access Classroom and Safari, and when they went to Safari, they could ONLY access the school webpage.

Yes this is what I want!! but, when i go into configuration profiles there's nothing there for me to change??? it says content filter but I cant open it..

you need to configure that payload. when you click on Content Filter you will need to click the "configure" button on the right.

@denice.clapper You need to contact whoever runs your Jamf server or someone who has a more elevated access than you. Sounds like your Jamf Pro Admin Account is restricted.
