bluemongoose Posted December 17, 2009 Share Posted December 17, 2009 I am correcting my DD workbook pg 62 of the Standards edition. Problem 4. The egg picture and the word problem do not line up???:001_huh: Quote Link to comment Share on other sites More sharing options...
MDMom Posted December 17, 2009 Share Posted December 17, 2009 Yep, I think it's a mistake. We did that lesson a few months ago and I penciled in a 4 in place of the 6. I hope I'm not missing something :glare: Quote Link to comment Share on other sites More sharing options...
bluemongoose Posted December 17, 2009 Author Share Posted December 17, 2009 Good I am glad you saw it too. I have been so sleepy lately with a sick toddler and a night nursing baby that I was unsure if I was just being dumb. LOL! Quote Link to comment Share on other sites More sharing options...
Spy Car Posted December 17, 2009 Share Posted December 17, 2009 Oh we're just a few pages shy of this lesson. I don't think I'll say anything and see. For those curious, the "pictorial" image shows 6 eggs remaining in a ten pack, and 4 broken ones outside the pack. Working on subtraction. The Equation is: 10 (fill-in the proper mathematical symbol here, represented to the child as an empty circle) 6 = [unknown quantity, represented as an empty box). So it would be 10 ( - ) 6 = [ 4 ] where you fill-in the missing elements. And in isolation it's mathematically correct. It just doesn't match the picture :lol: I'm very curious to see if my son accepts the equation as mathematical in the equation, or if the discrepancy will offend. Hmmm?

Dana Posted December 17, 2009 Share Posted December 17, 2009 We used the US edition of 1, so I don't recall whether we had the same problem or not, but wouldn't it work as the "whole" - "part" = "part" model? If the picture didn't show the broken eggs at all and asked how many eggs had been used, then you'd have 10 - 6 = ?? and it would match the picture. Maybe it just depends on what types of problems were nearby. Errata for the new texts are here and Jenny has been great when I've caught errors and emailed her.

It does still work as "whole - part = part" model. But the picture still offends our linguistic sense, since it shows 4 parts that have been taken away from ten, rather than six parts.

The Governess Posted December 17, 2009 Share Posted December 17, 2009 That problem came up for us last month. Dd5 definitely noticed it and pointed out that there were only four broken eggs. Maybe throwing in an incorrect problem here and there is a good way of seeing if the concepts they are learning are sticking. :D Quote Link to comment Share on other sites More sharing options...

bluemongoose Posted December 18, 2009 Author Share Posted December 18, 2009 LOL that is funny! Well, DD didnt seem to mind, she got the problem filled in correctly and didnt mention it. So I guess she passed the pop quiz... Quote Link to comment Share on other sites More sharing options...
Spy Car Posted December 18, 2009 Share Posted December 18, 2009 So we did these pages last night. My son filled in the "minus" sign and the 4 without blinking. Then pointed out the picture was wrong. What really pleased me though, was, of his own initiative (because I sometimes set this up myself) that he wrote out the "number bonds" alongside the equations for each of the exercises in this section. So what-ever "error" this might have been, I'm so loving what this method seems to be building. Bill Quote Link to comment Share on other sites More sharing options...
Kennic Posted December 19, 2009 Share Posted December 19, 2009 The error is that it is supposed to say how many eggs were used. Not were left. Somehow apparently the sentence got changed between US edition and standards edition, it does say "used" in the US edition. There is an errata here: http://www.singaporemaths.com/errata/ Quote Link to comment Share on other sites More sharing options...
