Xbox 360 Xbox games for 4 years help plz

[Holi]

I'm new to Xbox. I have bought Xbox 360 for my son. I have one month gold membership for free but I can't find any free games. How to get games suitable for my son age and is there a free way to download games?
Thank you

You should have waited for a Christmas deal on the Xbox one which is the newest but I take it your son is pretty young so for $20 you could buy MineCraft, the game never really ends and I played pretty much that for like 3 years and on the 360 there are indi games for a Dollar but none of this is free because there is pretty much nothing free sorry.

Hmm, Maybe kinect is the answer, Try all of the kinect games (Not horror for sure).
