Yes, and it depends:
*"Play is our brains favorite way of learning." -- ungrammatical; doesn't make sense.
"Play is our brain's favorite way of learning." -- the brain of each of us.
"Play is our brains' favorite way of learning." -- the brains of ours.
HTH.
Yes, you need an apostrophe.
To me, “our brain’s” doesn't make any sense because I can only interpret “our brain” as meaning “the single brain belonging to us collectively”. So I would only use “our brains’ ”. But different English speakers apparently have different intuitions about the acceptability of expressions like these.
As I mentioned in the comments, a related question is Members must use their own cards ,or, members must use their own card? I didn't look through the linked questions earlier, but now I have, and I have found one that I think is a duplicate: Our bodies' or our body's.
"Play is our brain's favorite way of learning."
In this sentence'Play' is a noun, 'is' is a verb and 'our brain's favorite way of learning' is a complement. Therefore there should not be an apostrophe.
