Singapore Math Challenge Workbook—Grades 3-5 Math Book, Tricks for Adding, Subtracting, Multiplying, Dividing Numbers, Using Patterns, Working Backward (352 pgs) (Volume 19)

Definitely a challenging book for 3rd graders (and even many 4th graders). They have good examples at the beginning of each chapter, and a bunch of practice questions in the same vein. I definitely will recommend if you want to compete in math competitions like math kangaroo etc.

My 3rd grade son learned a lot interesting math from the Singapore Math. It is a little bit chanllege, but it is fun. I would like to buy more Singapore math books for him.

very good book

Great in challenging your brainy grade school kid. American math are way too easy and this provide a window into what other country are doing in teaching kids math. Math learning has 2 components: repeat practice basic skill and challenge critical thinking. This provides the critical thinking portion. So why 4 stars? I bought 3+ and it is missing the 1st 20 pages. The replacement is the same.

The math that I learned when I was young. Didnt know now it’s called Singapore math lol

The book was listed as brand new one. However, what I reeived was a used one. Over 10 pages are missing, and one page with handwriting!!

Challenging Math questions teaches to think in a different way. I find myself solving the problems eagerly while helping my daughter.

I am doing a few questions each day with my 8 years old child. We are preparing for Kangaroo Math competition. He is understanding the questions after my husband and I give him hints. Still, some of the logic problems are very challenging even for adults. Example - Chicken & Rabbit A farmer has 80 chickens and rabbits. There are a total of 250 legs. How many chickens are there? How many rabbits are there? Answer - 45 rabbits and 35 chickens

Excellent book.

Only 1 problem /page... I really hoped I will find a great resource... but unfortunately it is not the case...

This is a great book to challenge students, they love this book, and it is a go-to for many maths-related activities.

I am a Montessori teacher and avoid workbooks, but like to link the children to traditional math work too. This book is perfect as it presents math puzzles which open a mind rather than close a mind.
