Forget about basic math start your young one with set theory, that is the way to go. I was surprisesd to see how the schools kinda snuck it into my sons early learning, unfortunately he does not seem to possess the math gene, but he is way above grade level with the reading (always has been). I remember teaching myself how to tell time before kindergarten and counting by how many times the swingset swang by. I remember being shocked when I had to reteach my son the times tables, that would be 4th 5th and 6th grade. Good luck and I also recommend the computer games, my son loved them.P.S> at 16 he still can’t write cursive.
