Really? Mine never gets hot. I wouldn't leave it on long either if the cord was getting hot. I cook mine for 24 hours. I will go longer if for some reason I can't take it out, cool it and freeze it in a timely fashion.You do 48 hours in the slow cooker, I think I would be afraid to leave it on so long. The cord area of mine gets kinda hot after 10 hours.
Common core math. I really don't understand it. I can get the answer faster the old way, without having to go around the block 3 or 4 times as you do with common core. I show my granddaughter (2nd grader) how to do it the old way, but she still has to do it using common core so that it won't be counted wrong. It reminds me of hooked on phonics. Our school used phonics back when my kids were going. They still have to ask me how to spell things since the hooked on phonics really messed with their spelling ability.
