I could present this to my son in a neutral, unemotional fashion, or I could present it with an "excitement" about the opportunity that he can choose.

I could leave this completely up to him, or I could tell him that Algebra is his best choice because more than half of Accel 7 is stuff he already knows.

They have not yet given me details on how many hours/days will be required in the summer.

How would you present this to your child if you were in my shoes? He's 10 years old, and pretty much all of 4th, 5th, and 6th grade math he has been unhappy about how easy and "boring" it is.
