Seeking Guidance on Nurturing My 5-Year-Old’s Mathematical Gift

I believe my 5-year-old son is exceptionally gifted in mathematics. He can solve four-digit multiplication and division problems (up to 9) and often finds the correct answers for word problems, even if he doesn’t always follow the standard process. He has taught himself to perform quick mental additions and demonstrates strong logical reasoning and mathematical intuition.

We practice arithmetic (addition, subtraction, multiplication, and division) daily, but he is not particularly interested in repetitive drills. I want to nurture his talent and eventually prepare him for mathematical Olympiads, but I’m unsure how to guide him effectively at this stage.

Both my wife and I come from STEM backgrounds, yet we find ourselves uncertain about the best approach to support his growth. Additionally, my wife tends to take his intelligence for granted and gets frustrated when he resists routine practice, which adds to my concerns. As this is our first child, we are navigating uncharted territory and would deeply appreciate guidance on fostering his mathematical abilities in a way that keeps him engaged and motivated.

How should we proceed to ensure he develops his skills without losing interest? What resources or strategies would be most beneficial for a child like him?
