Electrolysis equation for Chem IA2. Help!

Hi everyone,
for my chem student experiment I did copper plating with a copper anode and aluminum cathode in a 1M copper sulfate solution. How would you write the half-equations for this process? I tried but I don't know if it is right:
Anode: Cu(s)→ Cu^2+(aq)+2e-
Cathode: Cu^2+(aq) +2e- → Cu(s)

Also once you find the half-equations do you have to explain anything further?

Thanks!

Anode equation is correct, for cathode did you mean Al^2+(aq) + 2e- --> Al(s)?

I'm doing titration for my student experiment, so I would suggest you check out the high-level IA2 on the QCAA website to check if further explanations are needed.
