I am completely new to homeschooling. We will start this fall. My oldest son (7) has been in public school for K and 1st grade. We were blessed to have him in a wonderful school with awesome teachers. He excelled, was top in his class for reading and math this year and has always made all "E's" on his report cards. He loves school and loves to learn. I am pretty certain I should start him in BLHFHG but would like some feedback. He just turned 7 in May. He is an independent reader so I plan to use DITHOR. He scored 100% on the 1B Singapore test, so if I understand correctly I should order 2A/2B. I have been contemplating using Bigger but feel that with this being our first year homeschooling, perhaps I should be a little reserved rather than pushing him? Again, I would love thoughts on this!
I also have a son who just turned 3 in March. He and his older brother are polar opposites. My younger son is extremely active and has zero desire to participate in activities such as reading, playing with alphabet letters, etc. Usually the only time he settles down is when he is sleeping. I am planning to slowly begin LHTH with him, hoping that he will enjoy "school time" with his big brother.

I would greatly appreciate some thoughts. Thanks in advance!
