Cara4497 Posted October 18, 2016 Share Posted October 18, 2016 I'm trying to understand why the 10 is in the ONES column on page 88. I would have thought the 1 would go in the TENS column and the 0 in the ONES. It has been 30+ years since I've done elementary math so I am more than a little rusty. Any help would be appreciated.

smfmommy Posted October 18, 2016 Share Posted October 18, 2016 I have the original series so can't help you specifically, but the Master Books facebook page is visited by the author. I would ask there or email the company. 1 Quote Link to comment Share on other sites More sharing options...
silver Posted October 19, 2016 Share Posted October 19, 2016 It sounds like a typo. I have the old version, and all instances of 10 have the 1 in the tens column. 1 Quote Link to comment Share on other sites More sharing options...
pamela722 Posted October 21, 2016 Share Posted October 21, 2016 I don't have this book but I think what they are doing is telling a story and it will build on that. The 10 is in the ones place to show the children the 1 in 10 means 1 group of 10. Seeing it as a group of 10 before moving the 1 over may help teach the place value better. 1 Quote Link to comment Share on other sites More sharing options...
