KADmom, unless the school has specifically requested that you "fill in the holes" I wouldn't stress over them and I'd give him the summer off from math. If you find there are holes next year in school, work on them then - but I'm guessing they won't be an issue.
Re how to "get this kid to love math" - that's someth you can't really make happen - its something that's going to either happen within him at some pint in time or it might not ever happen - and really, that's ok if it doesn't, isn't it? I think math is so easily quantitative that it's easy for us as parents of high ability kids to expect our kids will e math superstars, but our kids are individuals and just being smart doesn't mean a child is going to love math. I suspect that you'll find as he moves on into e teen years and high school that he'll start naturally discovering the areas of academics he's passionate about - and even if he isn't all that into math at this level something later on in math might really excite him - or not, but eithe rway, it will be ok
Best wishes,
