Focus on Speed, Ratio and Proportion

I recommend every workbook and anything from Kumon. Their books are great, short and clear explanations that explain enough without wasting the child's time, clear and accurate assessment of the student's work through a point system in the books, plus there are answers and some solutions that help a lot. So far, I haven't come across Kumon's bad workbooks, although I've bought textbooks from almost every subject they offer. They are really grеat!!! Especially this book for grades 6-8 for text math problems, for Algebra and Geometry, which covers everything the children maybe missed and the children progress very quickly to a higher grade that they has not yet reached. I am very impressed ! I rarely have such opinions about any book! In the beginning it is difficult for the child with Kumon's books and they spend more time even for one lesson, but later the child begins to understand more and more and becomes pleasant and begins to become more independent if they don't stop perseverance in the practice of Kumon's books. I bought several books from this seller at the same time, so my delivery was free.

Great book for working through with your child. Very clear examples and answers to all questions in the back in case your maths is as bad as my wife's.

Excellent practice book! I love the Kumon concept of practice practice practice! My son really likes the daily practice and the assignments are not to long so that he can get it done fast but still practice the skill.

A Good book as is most other kumon book cover a few topics

Kumon is a very good program. Especially for homeschoolers.
