I don’t want him to get bored with education so I’m trying to keep him learning.

I would say that jumpstart is the best!!!! I am 14 years old now. But back when I was 11 and below, every birthday I would ask for a jumpstart game. My dad got me a jumpstart 1st grade hwn I was in the first grade. And it was AWSOME!!!!! As I went up to higher grades I bought the higher and higher grade ones (2nd, 3rd, 4th). Right now I have jupstart 6th grade. I don’t play it anymore but when I am really bored, I just grab the game cuz it’s still quite enjoyable.
