Screen cast to ipads?


I am searching for a solution to help classes of students observe Trident’s live video feed. When there are more than 4-5 students it becomes impossible to share in the wonder of exploration. TV worked well indoors, but I am hoping for a solution that allows the singularity gaming pad to cast to multiple device screens wirelessly. Is this possible?
I am having no luck with 1 iPad as I attempt to connect them via bluetooth. The iPad says connected for about 1-2 seconds and then switches to not connected.
Any suggestions would be much appreciated.
