NPC Human Guard, Male's page

Hey, so the other day my sister joked about using pathfinder to fill in her future kids' education since the current US system is starting to take out things like spelling, order of operations, cursive and probably a slew of other things. She was joking but I thought about and its actually a good idea. I don't want my kids stumped by simple things like times tables or making change as a cashier. Some basic stuff we thought of was like instead of saving throw rolls they have to answer a question right and for attack rolls, the lower they roll the harder the question, the higher they roll the easier the question. We also figure if their character gets killed, they're kids I don't need them taking time to come up with a whole new character. So instead, answer a bonus question, you're not dead and then answer more to get your health back up. So my question is to paizo pathfinder parents since I am not a parent yet either; how could I get my future kids interested into the game first and how about easy, rated PG campaigns for younger kids? Thoughts and ideas on a structure are also appreciated! :)

Thanks so much everyone! :)

So, my friends and I are starting a new campaign with all new characters after two of our people moved and someone wanted to make a new character. I'm trying out something I've never done before by being a Magus but her race is tripping me up. I'd like to give her the ability to breathe water and have an affinity to water. Much like Orin and Kaldur'ahm from young justice. But I'm having trouble picking and choosing which racial traits she would gain from her human mother and which she would gain from her merfolk father without completely overpowering her. I was trying to find a minus to give her but being half human she would lose the land-cumbersome tail of the merfolk. Humans don't really have any specific drawbacks due to there versatility and the best a could come up with is she wouldn't know Aquan having been raised among humans. Other than that I could take away the extra skill points and/or the bonus feat all humans get at level 1. I've decided she would not be eligible for any merfolk archetypes since she grew up on land.

Here is what I came up with. Any suggestions?
+2Dex, +2Con, +2Cha
Medium size
Normal speed
Normal swim speed?
Amphibious
Lowlight vision
Bonus feat at lvl1?
+1 skill rank at level 1?
