Singapore Math Challenge Workbook—Common Core Math for Grades 4-6

I purchased this to give my child extra practice over the summer. I skimmed the book. The problems look great - challenging, but not so challenging they would give up. My child has used the other books in this series before. Great resource! Makes them think! I highly recommend it!

Awesome workbook for singapore math. It really is challenging but I have no worries with this book that we might be missing pieces in our home school curriculum, or that my son is squeaking by rather than living up to his full potential. Quite happy!

Very good math project

You may hear the Singapore math from many people or online. But this is not that Singapore math. However, it still give students some benefits if they really use this book. This book 4 covers the same topics as book3 with different levels of problems. I bought both and I feel they are useful.

An excellent set of interesting and challenging questions!! My son (7.7 years old) was very interested in doing the problems. A fun way to learn mathematics.

Too complicated.

This is the best Math series that I have used. Step by step answers are in the book. Our kids have been using Singapore Math system for the past few years and are at least one year ahead of their class.

This was a very helpful book for my ten year old daughter. It was suggested by one of her friends, who is top student in her grade. She has been improving with her math skills ever since we received this book. We highly appreciated all that this book has done for us and recommends it to anyone who is interested.
