Put the male and female alone in a small room alone while she is in heat with food and water and leave them alone...let them out to go potty though..they know what to do

 He won't succeed unless she's ready to breed.. Is she "standing" for him... Is she flirty and "flagging"... If not wait a couple of days and try again.
 
If she is, and he's just to excited to get the job done... Then i agree, the best thing to do is to leave them together for an expended period and give him time to figure it out.  There are ways of assisting, but if you have no experience and no mentor to walk you through it, it's just to lengthy to try to explain here.
 
if you're determined to breed this pair, and time is running out, and he still just doesn't get... an experienced vet can quickly and easily artificially inseminate for you.
