As I'm not up with with way Apple does things can you tell me if an I pad can receive files via its USB or equivalent port via a OTG (one the go) connector?

This would seem to indicate the possibility:

If so then just cable the Android phone to the iPad.

OTG allows a device to act as a USB host.

On Android devices it means you can plug most any USB devises into them. Devices like Mouse, keyboards pen drive hard drives and other Android phones.

I see the Amazon add above for a Lightning to USB iPhone OTG Adapter mentions everything except Android phones and hard drives.

When Im traveling I copy Video files from my android phone directly to a portable 5TB hard drive. The phone powers the drive.

If your student is wanting to copy the photos to a iPad as a backup then a bigger backup would be a hard drive. If it is to view the photos on a bigger screen then a portable hard drive, after having the photos copied to it, can be plugged into a modern big screen TV.

The ideas that others have suggested of using Google photos means the uploading and downloading of photos to and from the cloud, which is far slower than directly connecting devices. If there are only a relatively small.numbers of photos it may be acceptable.

In my case I have over 10 TB of video files plus about half a million photos, so beyond what the free cloud services, provide. I find it cheaper and faster to use my own Raspberry pi $100 servers. Every few years I purchased a new portable hard drive where I pay about the same price, but get more storage capacity.

An alternative to servers is to plug a portable hard drive into your router, if it supports it.

Again I don't no how Apple IOS works but all my Android devices have access to multiple hard drives plugged into my router.

This would seem to indicate that IOS could also do it:

Yet another way to get photos from a android phone to a iPad, albeit long-winded, is to install a Micro SD card in the android phone, copy the photos to that card, take the card out of the phone and use a SD card reader attached to the iPad to copy the photos from the card to the IPad.

And another way again is if the Android phone and iPad are on the same wifi network use either file manager app to copy the photos.
