Singapore Math – 70 Must-Know Word Problems Workbook for 5th Grade Math, Paperback, Ages 10–11 with Answer Key (Volume 3) Review: Good for some extra practice with model drawing problems - I really liked this book. My 10 year old 5th grader is using it. I like how it lays out the problems, gives strategies up front and allows the student to try the same type of problem more than once to get it right. I re-used the problems later by just changing "names" and numbers in the problems to make up my own "revision" test. I highly recommend this to anyone looking to teach their child (and learn themselves) how to solve Singapore Math problems using model drawing. It took me a few tries, but I got the hang of it. If you want a more difficult book, you can get the Primary Math Challenging Word Problems book. Review: 5th grade math: using algebra? or using diagrams? - 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 11/12/22 I 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 is 2 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). ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #288,487 in Books ( See Top 100 in Books ) #973 in Children's Math Books (Books) | | Customer Reviews | 4.5 4.5 out of 5 stars (353) | | Dimensions | 8.4 x 0.38 x 10.6 inches | | Edition | Workbook | | ISBN-10 | 076824014X | | ISBN-13 | 978-0768240146 | | Item Weight | 12.8 ounces | | Language | English | | Part of series | Singapore Math | | Print length | 160 pages | | Publication date | June 1, 2009 | | Publisher | Frank Schaffer Publications | | Reading age | 9 - 11 years, from customers | ## Images ![Singapore Math – 70 Must-Know Word Problems Workbook for 5th Grade Math, Paperback, Ages 10–11 with Answer Key (Volume 3) - Image 1](https://m.media-amazon.com/images/I/81FWI-OE+bL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good for some extra practice with model drawing problems *by S***M on December 10, 2013* I really liked this book.

It teaches you how to solve some problems using algebra but without having to use variables. ## Frequently Bought Together - Singapore Math 70 Must-Know Word Problems Level 4, Grade 5 - Singapore Math Challenge, Grades 4 - 6 - Singapore Math Practice Level 5A, Grade 6 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/8457637-singapore-math-70-must-know-word-problems-workbook-for-5th](https://www.desertcart.is/products/8457637-singapore-math-70-must-know-word-problems-workbook-for-5th) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-05-04*
