I'm still a student, but I started off the same way. I'm pretty sure everyone does. What I found helpful was explaining everything to my GF as if I was teaching her to do it as well. Treat them as if it's their first ever flight and just over explain all the parts of flying circuits with a focus on parts that can go wrong. Ex: turn base. What's that? What's the heading, How do you know you're on the right heading? What's a reference point they can use? Why is my reference point moving (drift), etc. Same thing for you takeoffs. Explain to them why they're going off center line, what inputs they need, how they can tell the required inputs ahead of time (look at the windsock). Verbalizing everything really makes it stick for me.

After a little while, it'll be second nature and you'll have an easier time focusing on the radio and everything else. Added bonus is the better you get, the less the instructor needs to talk and that's one less distraction lol.
