amo_mea_filiis. Posted November 1, 2011 Share Posted November 1, 2011 What is with all the estimating in division? Is there something wrong with doing the darn work? I'm sitting next to dd watching her do the work, then we submit the assessment, and she gets them all wrong! I thought she was right. :confused: When she does any division, she has to multiple to check, so she's getting the actual answer, but we're lost on the guessed answer.

happyhomemaker Posted November 2, 2011 Share Posted November 2, 2011 Does her text not give any instructions for the estimation? When dd is instructed to estimate for multiplication, the text says to round any 3 digit number to the nearest 100 and any 2 digit number to the nearest 10 and then work the problem. How is your dd getting her estimation? Quote Link to comment Share on other sites More sharing options...
amo_mea_filiis. Posted November 2, 2011 Author Share Posted November 2, 2011 The text doesn't explain it well, and the lesson relies on video (Brain Pop, or through the school) over text. I'll review the lessons this morning before dd starts to see if I can better understand it on my own. Quote Link to comment Share on other sites More sharing options...
cathmom Posted November 2, 2011 Share Posted November 2, 2011 my dd was annoyed with all the estimation in MUS - she'd rather just do the problem than (essentially) do the same problem twice LOL! Quote Link to comment Share on other sites More sharing options...
Chris in VA Posted November 2, 2011 Share Posted November 2, 2011 Agreeing with WendyK--my son had trouble with large division problems at first, because he could estimate what number to "put on top," as he put it! So it's a useful skill in that way. And it really does come in handy when you get a wild answer and know it *couldn't* be right. Quote Link to comment Share on other sites More sharing options...
jennynd Posted November 2, 2011 Share Posted November 2, 2011 i hate estimate. that is one concept I don't think make sense in math world at all. Quote Link to comment Share on other sites More sharing options...

Dd and I have a poor sense with numbers, so it doesn't help at all. We will multiply to check the answer and if it's way off, I'll notice before I'm done.

QueenCat Posted November 2, 2011 Share Posted November 2, 2011 Estimating has practical applications in the "real world". Especially when shopping. Quote Link to comment Share on other sites More sharing options...
Haiku Posted November 2, 2011 Share Posted November 2, 2011 My dd, in MM4, had trouble with estimating, too. (Well, she said she did. I thought she did fine. I just think it was the first math concept she encountered that wasn't easy for her). With three-digit numbers I had her round to the nearest 50, and with two-digit numbers I had her round to the nearest 10. She asked for extra practice problems, and she worked on those for two days, and then she decided she understood. I agree that estimating is a very useful skill. Since your dd is in a cyber school, can you ask the teacher for guidance? Tara Quote Link to comment Share on other sites More sharing options...

My kids, too. Once they showed me that they could estimate I told them to skip it. Quote Link to comment Share on other sites More sharing options...
