I'm considering switching out of Saxon and into Math U See. After reading the new edition of TWTM and her emphasis on conceptual learning, I feel like in the area of place value (which almost all of math seems to hinge on), Saxon is really weak conceptually in how they teach it. My son is in 2nd grade and doing Saxon math 3. He is extremely bright when it comes to math so I never really worried about him conceptually, until I started reading more about it. He seems to be doing great with Saxon, but I'm just worried it's not enough conceptually. I know in TWTM it says Math U See is a good option but that you should supplement some. Does that mean on memorization of math facts? Or something else? I don't want to be constantly having to come up with extra stuff. My daughter started Saxon 1 this year and I think the jumping around from topic to topic is confusing to her. She is definitely going to need more of a Math U See manipulative based program.
Any thoughts? I'm fairly at peace with my younger student switching out to Math U See, but am slightly panicked about switching my son who has only ever done Saxon. Because he has much more of a math, science, computer mind, I want to make sure I'm doing the best thing for him. You used to hear homeschool communities and many classical groups rave about Saxon, but now that tide seems to be turning.
Also, comparing the two (Saxon and Math U See), it seems like Saxon covers way more and that Math U See is so quick and "easy" with not much to it. Compared to Saxon, I feel like we would missing A LOT of stuff using Math U See. Or is it just different across the whole curriculum?
