yellowperch Posted March 5, 2011 Share Posted March 5, 2011 When does Singapore address order of operations? I can't seem to find it. Thanks for your help. Quote Link to comment Share on other sites More sharing options...
nicurn Posted March 5, 2011 Share Posted March 5, 2011 They do because I remember covering it with my son. I think it is in the 6B? book, but wouldn't swear to it. Quote Link to comment Share on other sites More sharing options...
Ohdanigirl Posted March 5, 2011 Share Posted March 5, 2011 They begin doing so in book 5a. I checked my copy and I believe it was in lesson 6. HTH Danielle Quote Link to comment Share on other sites More sharing options...
nd293 Posted March 5, 2011 Share Posted March 5, 2011 Definitely in 5A - we are doing it this week. Dd says we didn't do it last year, which was Primary 3. We skipped Primary 4 entirely, so not sure about that one. Quote Link to comment Share on other sites More sharing options...
Dana Posted March 5, 2011 Share Posted March 5, 2011 I do think it was covered in level 4 at some point too. It's introduced in 4A standards (whole numbers). Quote Link to comment Share on other sites More sharing options...
Crimson Wife Posted March 5, 2011 Share Posted March 5, 2011 It's introduced in 4A standards (whole numbers). Yep, it's in chapter 1, section 5 of 4A SE. The U.S. edition might have it later in the S&S. Quote Link to comment Share on other sites More sharing options...
