We homeschool and supplement our homeschool curriculum with free online courses from Khan Academy and we also use the free Imprimis publication from conservative Hillsdale College for discussing political and social issues.
Google them and try them out! They’re both free so you’re not on the hook for anything!
(I have to admit I have learned A LOT with both resources!)
khanacademy.org
Khanacademy.org has some good material on the sciences. As to history and those subjects where liberal bias creeps in, I will defer to others.

Memoria press has a good web site. Good for logic and classics.
You could probably adapt the freebie Hillsdale college courses on the constitution and federalist papers for a 12 year old.

The Daily Grams books are the best quick daily Grammar review out there. It gives a daily worksheet to keep concepts fresh and keep students practiced in grammar and punctuation.

Google the well trained mind forum. Lots of good info there and you can ask questions.
Agreed that going through the Hillsdale constitution course together over the summer would be awesome.
Check out the LSAT prep books - some are just full of great logic puzzles.
Go to any homeschooling convention near you and go into the resources hall. Bring money, lol. There might be some awesome books, games, etc. (You probably can get into the resources hall without paying for the convention.)
Here are the resources we used for homeschooling and supplementing the summer...

If you’re worried about math...get a Saxon Math book and start using it with him. You can get the older version of the books on ebay. Here’s a link to a test that will tell you which book to start with:

When we were homeschooling, many moons ago :), we did Saxon math year round. Each new book, we’d be able to skip the first lessons, I’d just have him take the test till we got to a test he couldn’t do and we’d start at that lesson. They are very repetitious and that is the beauty of the books, IMO.
After Saxon Algebra II, just before what would have been 10th grade, my son tested into College Algebra at the local Community College, and all his higher math classes were taken at the college (with the Dual Enrollment policy, tuition was free and if I would have had to teach Calculus and Analytic Geometry, my head may have exploded.)
I think what you’re planning on doing is a good idea. We mostly did school year round, didn’t take long breaks, and no breaks from math.
It's summer..just make sure he (is it your son, or daughter?) outside playing,..lots of physical activity..maybe a program at your local Y..try and do some stuff with him on weekends..museums, field trips..camping.
Encourage him to read...anything...get him away from the boob tube and the computer.. Try Rush's "Revere" books..he'll learn REAL American history..
IOW..don't overload him..he's a kid..
