X-Wing - Introducing List Building to a 5 year old

We just got Penny's report card back earlier this week and she appears to be doing well.  Her social skills are also meeting expectations which is great as my wife and I were worried because she's an only child and has not had much interaction with peers outside of pre-school and kindergarten.  She can count fairly high in both French and English which is great and her addition skills seem to be on par with everyone else.

As a math teacher I'm ok with that but I'd like her to be better at math than her peers.  Call it pride if you will.  So in that regard I've decided that I'm going to introduce proper X-Wing list building to her soon.  Not sure how far I'll get though but from what I have seen her do and the report card comments she should be able to add tens (so add like 20 + 10) and she can already do ones addition (things like 1 + 4, and 5 + 2).  Shouldn't be too far of a stretch to do something like 12 + 23 (a Bandit Z-95 + Red Squadron X-Wing) or 16 + 5 (HWK-290 with Ion Turret).

My plan is basically to give her the points value for one of her ships and have her add upgrades to it and see what the new total is.  If that goes well, we can move on to adding the costs of ships together and hopefully get to a point where she can pick ships that add up to something close to 100 or whatever points total we decide to play at that day.

So the next game we play will be with a list that Penny makes herself!
