I setup the wifi AP to block youtube for his computer for certain time period.

Also, I reward him with game time / RC air plane building project time with me if he did certain % of Khan Academy each weekend. He's 4th grade and finished 35% of 6th grade math himself and did some javascript program course on Khan Academy.

Interesting, my son is in the same grade, 4. Would you mind sharing the Khan courses your son follows? Maybe I can get him do some coding. I'm a coder myself and I know this can be fun. Thanks.
