Resources for kids education Most of the questions on MSE about educational resources are for high school. At least I haven't found questions which deals with sites on very elementary mathematics. 
I will be grateful if someone provides me with list of educational resources for kids - e.g. of the level of kindergarten, primary school and junior high school.
If you think that this question is not for MSE, tell me were is it appropriate to ask?

Here are some things I found in a few minutes. I'm also including what seemed to be the best google search among those I tried.
