This is how I taught my daughter binary when she was 6 years old. It stuck with her and is the one thing I taught her that I can point to as giving her confidence in math. When I was satisfied with her retainment, I bought her one of those, "There are 10 kind of people..." shirts. She still wears it.
She has yet to figure out why my wife and I laugh when she gets to 4.
That is awesome. I feel that kids today are expected to be successful but not really learn; at least here the US. Though, in my daughter's school they are learning simple circuits in the 4th grade.
Thanks! She worked the code.org lessons and has been working through codeacademy lessons recently. She wants to build a game with me; so, it is way to have productive quality time together.
