In my opinion, this problem is pushing the limit beyond which bar model diagrams are not useful, and just-plain algebra works better. I suspect that is why the book gives the diagram, rather than expecting the student to produce it.
It is useful for kids to understand that ratios can be split to make equivalent ratios -- that 5/6 or 10/12 or 15/18 all name the same relationship. Then the student can use her knowledge of equivalent fractions to identify other similar ratios, and maybe make up a couple similar-ratio problems of her own.
Making up problems is a great way to wrap one's brain around a challenging topic.
I struggle with this a little with Singapore b/c often I think using algebra would be much easier but having too many options has proven challenging for my daughter. The bar diagrams work with her brain.
We will review this one along with equivalent ratios tomorrow.

Without the picture being clear enough on my screen, I had to do it trial and error a bit. and for some reason my brain went to 20:24 . That didn't work. so I tried something else. First thing I did was write down several ratio. I even did quick bar (blank lines for me) to help my brain click.
And that trial and error can be part of the process to learn how and why it is working in my experience with US edition of Singapore. I don't think it was supposed to be obvious to be 15:18 on first try (for average student) so the picture was there as the hint. If I were writing a home guide for it, I would encourage parent and student to try a trial and error process and give the hint about "which of those equivalents would be the same as 1 plus a factor of 28" and discuss that angle a bit. There may even be some other obvious thing that didn't occur to me as a hint.
But one has to write down some equivalent ratios and try for it. and it's ok to not get it right the first time. I seldom did in the US edition when helping my dd.
I don't know if the way I think and talk it out is helpful or not. But see if some of those insights talked out loud together
Thank you - very helpful and very reassuring. I felt like I was missing something.

Yes I think that does help - thank you. With the picture both my daughter and I understand the answer but I wasn't sure how they knew to make the equivalent ratio 15:18 as opposed to something else. I am not sure we would have been able to do it without the picture. We are going to work on some more tomorrow. I really wish this level of Singapore had the Home Instructor Guider. Thanks again.

Can anyone help me with this problem from the Singapore 6A STD textbook? There are errors in the answer guide and I am not sure I am understanding what I see in the textbook. I understand the answer but I can't figure out how to decide where to divide the units.

Purdue's OWL website is a fantastic resource for writing and grammar, and has a good page about infinitives here, which should answer all your questions: https://owl.english.purdue.edu/owl/resource/627/03/
That is a great resource!

We are using IEW level 2 for 4th and 6th grade. I think if you have done it before, or most of it, it would be too repetitive. And fwiw, I haven't had to adapt any of the writing for my 4th grader so if you do use it I would look consider looking at level 3.

Is EIW Essentials in Writing?

With my youngest I used Miquon for about a year and a half and Singapore the entire time. If I had discovered Miquon earlier I may would have used it exclusively with her and then moved to Singapore.

So far I am loving IEW. We are using Level 2 for my 4th and 6th grader and I think it is going to work out well. They are getting a little tired of writing key outlines but I think it is very good practice for them.

We didn't use the video sequentially. I usually just pulled one up that would help with a concept and/or for extended application of a lesson.
This is what we did also. I loved those videos and I think using the rods really helped my younger daughter. I wish I had used them for my older daughter also.

Sounds like a great option! I have checked out the book from the library but we didn't really get to it.
Want to combine 6th and 4th graders for grammar - suggestions?
