(1) For Math we used the venerable Saxon Math by John Saxon. These are orderly, incremental, comprehensive. I believe this builds orderly mental habits and will not frutrate youir child by being too hard, or bore him by being too easy. You can take it at the pspeed you judg best. You can make quite sure your kid "gets it" before going on to the next lesson.
For Language Arts, a.k.a. English, we --- like many FR homeschoolers --- used Seton, plus everything, everything, everything else. The way to do reading is: do a lot of it. Read stuff that engages the imagination, including the moral imagination and the historical imagination. We liked OLD books. We favored stuff written before 1960: immensely richer, more sophisticated vocabulary, and little or no PC crap.
Provide plenty of time for kids to explore and discover on their own. To assist them in this endeavor: have anothe rkid or two.
Nuff said!
“concurrent”. Yes, we homeskoolers are grate wit teh sspeling....
