Learning path for a comparatively brighter kid

Posting this in the Pune sub to get inputs on any offline recommendations on this topic, as I am based out of Pune.

So I don't want to sound like boasting but my five-year-old son is a little too ahead of his counterparts very inclined in mathematics as a subject.

I want to make sure that he gets access to all possible resources to help him with his learning journey. Any parents who have taken courses or any specific learning tracks that can be referred to ?

As parents we are not pushing him to do things in studies just for the sake of it so no expectational pressure here. I just want to present options for him to learn and he can choose whatever interests him.

TIA
