For those with 4-7 year olds worried about the homework thing: it’s much easier if you give them a head start. (ie. once they can read and count on their own - easier to them to mostly figure things out and keep up.) Before kindergarden, or during the summers try:
Reading: http://headsprout.com/ - smart computer program teaches kids to read. Free trial (good for seeing if your 4 or 5 year old is ready yet). Minimal cost. Kids like it and think it’s a game. Minimal parental work involved (ie. program does it all, sends you progress report emails. All you have to do is if the computer says “say it out loud” and your kid isn’t, holler over from cooking dinner or whatever and tell the kid you want to hear them saying it out loud). Works like a charm.
Math: I don’t know of any websites for that, go the old fashioned route and get some workbooks and teach them yourself. Or even get out a roll of pennies and teach them how to count and add and subtract.
