It's so hard to say at this age nessa - it just sounds like buoyant toddler behaviour to me, with frustration over communication issues, perhaps from both you and your DS. Why don't you ask your childminder if you can have a meeting to discuss his behaviour and a plan of action? Then either set up a time outside of pick up and drop off, or a phone call one evening.
You all need to be on the same page with regard to discipline and consequences, I think. And any CM worth their salt would agree to use at least basic sign language. You may even be surprised, I know I was amazed by my DD's preschool report, she seems to behave very differently there - much more reserved than she is at home.
It's hard to say what's causing his frustration but as others have said I would spend lots of time talking about your routine and your day at a point when he is calm - like "isn't it nice to wake up when you've had a good sleep? and then we get to go downstairs and have breakfast together, and then get some clothes on, isn't that lovely, what's your favourite thing to have for breakfast?" etc. It sounds inane but I find it subtly reinforces the plan. With my DD, who is still waking up in the night, we have been working on talking about what she can do to get back to sleep when she wakes up in the night, etc. It really helps us.
As I said, for us it also helps to build in some time when we're just playing together, not trying to get on with housework, and I try to set things up so I can just say yes - to reading, stickers, playing outside, watering plants, painting, whatever it might be. It's probably not relevant for your DS as he's younger, but I only let her play games on the ipad every now and again as she gets quite frustrated and cross if she does that for more than a few minutes - the same with screen time, it makes her cranky.
