    Daily drillsThe exercises were good practices for home use to supplement what was learnt. Helps the child to fall into a simple daily routine to focus and work through 2-3pages.

  2. True Revu

    Good Supplement, Minor DownsideThis is a good supplement for extra practice for calculating fractions. Only downside (reduction of 1 star) is that it would be nice to have more than a handful of the same type of problems to work through, before the book moves on to another concept. Otherwise, all good.

    Nice Study Material!My son is in a 5th grade. He is very good at math. Since I am working full time, I ask him to do several pages per day in addition to his home work/project etc. Kumon emphasizes repetitive work. So it is rather simple, but it helps kids to acquire needed skill to be good in math. I highly recommend this book.

    Good study supplementGot these at the recommendation of our son’s tutor. His test results are gradually improving, so I guess they’re helping him learn the subject material.

    Great fraction workbook for Grade 4 curriculumStraightforward instructions and decent number of practice. My daughter used this after finishing fraction section in a general Grade 4 math workbook to further her understanding and manipulation of fractions.

    So far so good.bought for my 11 year old in sixth grade, to help with her math class this year. So far so good.

    Too easy for 10 year oldKind of easy for a 10 year old. I think this should be targeted more to 9 or under kids. 10 year olds will not learn anything from this besides repeating some work they have done. The flow is decent though, they start from simple and then go a bit more complex on all different variations of adding, subtracting, multiplying and dividing fractions.

    Kumon is helpfulAfter the Kumon workbook of grade 5 Word Problems, we got this fraction workbook for our son. Choosing Kumon Method has always been our top priority. This book includes practice of reducing and calculating fractions. Truly, there are over sixty pages of practice! Concepts are introduced gradually and built upon one another so that my son can advance through fraction without frustration or anxiety. My son also does math practice in Beestar (a wonderful website as a supplement of practice from school and Kumon workbooks. It is probably the best among the many learning sites. The worksheets are well-designed and have both time and accuracy targets set for your child to practice. Thanks to all the wonderful practice, he has shown great progress in math.

    Easy but a great workbook to learn the basicsIt took my 10-year old (just finished fourth grade) four one-hour sessions to finish the whole thing. Some concepts were new to her such as fraction multiplication, but the one example at the top is clear enough for her to learn how to do it. She didn’t need any help. She is 99 percentile in math at her grade level. This book is not hard for her, but it offers a clear path for kids to learn the basics.

  31. Danielle

    Lots of problems to practiceThere were more than enough problems to work on for practice. It was helpful for both my fourth and fifth graders.

    I love KumonArithmetic skills are crucial for understanding and being flexible in mathematicsKumon’s gradual progression from simple to more complex has ensured that my daughter is strong in math at schoolThey don’t do nearly enough practice at school so please please get your kids practicing arithmeticI teach special Ed students and I have to say these books are great! The paper is thick so that it is easier for students with writing output issues and the layout is not distracting or too busy for children’s eyesI highly recommend kumon
