Ever since my DS5 was 2, he LOVES to be "quizzed" on trivia, math, spelling, logic questions, etc....this is our routine whenever we're in the car. My DD2 was feeling left out, so she insists on questions also. I run out of questions for her though...so I resort to body part identification.

DS5 needs to synthesize knew knowledge verbally, and wants to discuss new things he's learned often past my own mastery. Mort conversations end with an Internet search. Thank goodness for smart phones.
