PanzerAzelSaturn - my ds9 was born with visual deficits. I've taken him to 6 eye doctors (three ophthalmologists and three behavioral/developmental optometrists) in two different states since we've moved. Ds was born with a left eye injury and some other issues that affected his vision.
Ds9 was in visual therapy between 4-6 yrs old. He also couldn't deal with a lot of visual stimulation or a lot of text or visual instruction when he was 5. I had to be a bit selective with the homeschooling curriculum and limit his screen exposure as well. And that is still somewhat true today.
I didn't use Singapore Math. I know others here have found it to be useful. I bought a fairly inexpensive general curriculum series - Learn at Home - for each elementary year. I supplemented the series with some online series like e-learning for kids or PBS's Cyberchase. I didn't have ds do a lot of worksheets or math drills each day. He didn't need much repetition either. So I tried to work around it.
When ds was in the Montessorish private gifted school, they used xtramath.org and Dreambox. Ds just wasn't fast enough with math facts at that point to move beyond addition and got extremely frustrated. I decided to forgo any math fact drills until he was older. So far, I haven't gone back to doing the math fact drills. At some point in the future, he may have to do the SAT or ACT and then he'll need to have those math facts mastered but until then I'm not overly worried or concerned because ds is far ahead in math.
IF you don't like Singapore, don't be afraid to ditch and try something else. IF you do like Singapore, then that's excellent and one hoop covered so to speak. Also, never be afraid of doing something out of box or many grades ahead.
Drugs. I had a 2e expert ask me if I had thought about medication for ds due to the ADHDish behavior. I then asked her about neurofeedback and any discussion about medication was dropped. Ds has not been on medication. Like you, I agree that I'm only one who has to deal with him and ds is generally happy and cooperative.
I think your ds's idea writing out sheets of math work for you do - is excellent and one I would encourage. Let him feel like he's in control by organizing you. It's a fantastic way for him to learn and be more receptive and cooperative. It's makes your life much easier and go much smoother.
