Division withTwo-digit Divisors

Hello 4th graders! I would like you to watch two videos about division with double digit divisors - the first is me talking you through a division problem while estimating.  See if you can catch the mistake I made when I divided 15 into 85 (hint - it has to do with my estimation/rounding). I'll give you a piece of candy if you write the mistake down correctly on your note sheet. :)

By the way, I did make another mistake when I assigned the practice problem (eek! so many mistakes - I'm just getting used to this, I apologize!) The mistake that you must catch to earn your candy is when I divided 85 by 15, not the practice problem. (This is in the youtube video).
