The concept of infinity for a 5 year old
$begingroup$
My son, who just turned 5, has been interested in the concept of infinity since long. He asks me a lot of questions regarding infinity. For example, not accepting my infinity + any number = infinity, he asked me how old I will be when he himself becomes infinity years old.
How should I explain to him this concept that resonates with his previous understanding of mathematics. If it matters, he knows how to add and subtract very large numbers, knows about negative numbers and has figured out tables of any number less than 100.

I guess the former, since he is not satisfied with the latter explanation. Moreover, my thinking is to raise him one level up on his own ladder.

I would concentrate on other things instead of beating heads against the infinity wall. He doesn't have mental ability or background for a sophisticated explanation and simple one's like "too big to count" are not completely correct. Give it time.

This does not directly concern the $infty+1=infty$ issue and I am not certain that I understand what you mean by his previous understanding of mathematics, but I wanted to give the following suggestion:
- Ask your child to name the biggest number he knows (besides $infty$). (Let's say he answers $1000$);
- Tell him to add $1$ to it;
- Ask him again what is the biggest number he knows. (It should be $1001$).
Repeat the process a few times and he should realize at some point that he can do this indefinitely. He can just keep on adding $1$ for free. It doesn't matter if he can't name the numbers eventually, as long as he understands that the next number is one more than the previous one.
While this does not necessarily show the various types of infinities that might exist, I think the idea that you can "keep on going" is a fair definition of infinity for a 5 year-old. It's not too hard to understand and it illustrates that infinity is not a number like $1$, $2$ and $3$, but rather an idea: infinity is what you get if you keep on going forever. It is certainly better than the belief I had as a child that infinity was the biggest number; there's no such thing as the biggest if you can keep on adding $1$. I hope this helps in some way!
