We use old cardboard boxes and Lego pieces.. nobody gets any sweets

Sweets easier. How long was it since you handled kids?
The answer is four sweets, uhm I mean three sweets...

Hey - I'm holding the bags, and I'm taller than they are!
(And I can eat sweeties faster it I want to...)

Try it again:
Box "a" contains two items cats, box "b" contains three items mice, how many items have I got if I add what's in box "a" to what's in box "b"?

Still five items. Both are probably derived from "animal" which is derived from "object" anyway

Probably the three smaller items will be integrated with the two larger items if you put them together. Would you still call it five items after the integration process is completed?

Why not take it one step further: You put two cat items and three mice items into a closed box with no way to inspect the interior. Once you have closed and sealed the box, you will be unable to determine the total number of items in the box at any given time, until you break the seal.
If Schrödinger had designed sucn an experiment, he probably would have suggested two large dog items and three kitten items - rumours are that he wasn't very much in favor of protecting cats from harm.

"Pointers and memory addresses are a future topic Laugh | "
There are those that never ever get the concept of pointers. These people usually switch majors from programming to marketing.

I never understood the fuss about pointers, they always seemed pretty straightforward to me.
Trying to teach a 6 year old about hex or binary is probably pushing things a bit though

You can tell him the story with a bucket a which has 2 liters in it ...
Maybe he got other talents like singing or crafting things.

My son has a BS in Computer Science. Many years ago when we had that conversation it went like this:
Me: Let a=2 and let b=3. What's a + b?
Colin: 5. Get out of the way old man, I have an algorithm to debug!
The kid always was a quick study...
Like someone else wrote - memory addresses and pointers are probably a bit too advanced. Stick with a container appropriate to the age.
Contrary to popular belief, nobody owes you anything.

When I was first exposed to programming, I had the hardest time understanding how a computer new "what a is." One day, I just got it.
Here's what you do. Take two bowls, and label them "A" and "B" (actually label them, don't just say, let's call this bowl "A" and this bowl "B"!) Put 2 lemons (or apples, or whatever) in bowl A. Put 3 in bowl B. Ask your son how many lemons/apples/whatever are in both A and B. Then ask your son what A+B is.
Label a third empty bowl C. Ask your son to physically express "C = A + B" by moving the fruit from bowls A and B into C.
I'm sure he'll get it. Explaining all about memory address stuff is way to abstract without tangible, physical memnonics (or whatever the word is.)

Yes, and if you use a mix of apples, lemons, oranges, etc. you can refer to it all as "fruit" and then go on to talk about class inheritance and so on... Brilliant!

Does he know algebra?
What exactly would you like to explain?
Variables are an abstraction for a model that we use in math, programming and other things.
Talking about A and B allow us to think in general (abstract) terms.
I think that was astute for him to ask why not just add 2+3 together if he doesn't understand the need for the abstraction.
I agree with Mark's line of explanation, use something tangible.
To tie the entire argument together, where does the answer get stored?
If the equation is A+B=C, have a third bowl labeled C, place the bowls A and B inside of C.
How many oranges are in C.
A is still equal to 2
B is still equal to 3
C is now equal to 5
And no laws of physics had to be broken to magically produce 5 new oranges just to assign the answer to C.

Just found where I discovered variables aged 8.. on page 58 of this[^].

It might be time to try the Father Ted "small cow and far away cow" test.
It always gets me and if he passes it he's probably fine.
