### ⭐⭐⭐⭐⭐ 5th grade math: using algebra? or using diagrams?
*by S***A on July 7, 2020*

My son is 9yr (will be 10yr in 2months) and will be 4th grade soon. He finished the spectrum math grade 6 recently, and I got this to review 5th grade math using word problems before starting another grade 6 workbook. After two questions, I am debating whether to hold it until the end of 6th grade (or 7th grade) level or just do it now.** update on 11/12/22I used this book when my son fishied 6th grade level math.. I ignored the answer explanations, and taught my son to use algebra to solve problems. Very good problems for prealgebra level. Nor for 4th grade level. I don't think the answer explanations are right way to teach. However, I liked it, so I ended up buying the next two levels of Singapore math word problem workbooks.Why? Questions are not too difficult, but it looks better to solve using algebra concept.1st question is2 diamond rings + 4 silver rings= $1440 and 1 diamond ring + 1 silver sing = $660.My son combined numbers back and forth in his mind, and got the correct answer after trying two incorrect answers.The way to solve would be 2d + 4s=1440 and d+s=660 --> d =660-s --> 2(660-s) + 4s=1440 --> 1320-2s+4s=1440 --> 2s=1440-1320 = 120 --> s=60. I would say this is almost 7th grade math. The solution shows diagrams to solve this problem without algebra, but it looks a bit non-mathematical for me. It looks more like puzzle questions. Most questions are similar pattern. Would it be better to try this type of questions now and will it help him later understand algebra better? or, would it be better to know algebra first, then solve using algebra?This is the first time I purchased Singapore math workbook. I checked other level singapore math workbooks, and found that it's all similar style. The suggested solutions show diagrams to solve math. I am not sure if I want to teach my son 5th grade level using such diagram concept. Still debating whether to use this workbook to teach my son algebra after grade 6 level or use it now to practice the suggested methods (using diagrams).

### ⭐⭐⭐⭐⭐ Interesting and challenging
*by I***E on August 6, 2019*

I love this book, while my daughter hates it. It challenges your mind and you have to use your brain to solve these problems, which are not difficult at all but slightly different from the typical word problems. Most of the problems LOOK difficult at the first glance, but they are not. At the beginning I was not happy with the provided solutions which are mostly based on drawings and diagrams, but these solutions are simple and elegant. You still can teach your child a traditional method, when you make a system of 2 equations (as a 4th grader she was not familiar with the concept), but I found the approach used in the book more simple.

### ⭐⭐⭐⭐ To was too hard for my 5th grade to be
*by E***R on August 30, 2013*

I bought this book for my 10 years old who will be in 5th grade after summer. She likes problem solving and good at it too. But this book seems too hard for her. I will wait for few months then try again.
