I have used this in my class several years and really like them.
Sandy
If the student does all the sections it is easy to spot their specific area of struggle (if they have one).

He liked it so much that he wants to learn Math concepts using these books.

One of my kids used the whole fractions set for extra practice and review, and presently the younger child is half-way through it (in additiotion to using a complete math curriculum which gives not enough practice). The older loved this approach so much that he requested to do the Algebra set after trying three different algebra curriculums.

--

"Key to..." is a series of consumable math workbooks that focuses on single topics. There are no grade levels associated with them, they go by topic (i.e. Key to Fractions). You need to know that if you want to buy them as you won't find them listed or labeled by grade level. That is also a good thing because there is no stigma for the student if they need to practice fractions they won't have to be subjected to doing some workbook that has a lower grade level than they presently are in. The teacher's key with the answers is sold as a separate booklet.

There is a short and simple explanation of the math concept then practice is done on that concept. The book move along in progression from concept to concept, starting with basics and going to more advanced. If a student needs practice in one area but not the easier area it is easy to navigate through the book and to skip over certain sections to go to the harder material.

If the student does all the sections it is easy to spot their specific area of struggle (if they have one). This makes it easy for the homeschool parent or whoever is using it to realize the issue may be with just dividing with fractions or if they still need to practice simplifying fractions, or whichever specific content area is the issue. Once you know what the specific issue is, further customizing the practice or re-teaching just those concepts is easy to do.

This is a great way to teach fractions. I myself, hated learning them. My kids took to these books and got through them pretty quickly. I do wish there was more work and rather than just a few books, a longer set like the algebra set. If you hated fractions or want to give your students something they can do on their own without too much involvement from you, this is it. I would suggest adding some websites or other workbooks to really give more practice. If your student doesn't need a lot of repetition, then give these five stars. Now, the algebra set is AMAZING.

My 12 year old daughter did very well with this series last semester. She deals with extreme learning disabilites especially in math, so the repetition was very beneficial to her!

I'm using this two ways. One is to remediate my teenage son's math education. He just needed to focus on one area longer than his public school career allowed so he fell behind in math. Not only is he filling in the holes he had, but he seems to really understand what he's doing and why. The other way I'm using it is to TEACH my 10 year old. She has never seen fractions before this (although I will allow that she is more "mathy" than my other children). These lessons produce FAR less tears than anything else we've used, either in homeschooling or while she was in public school. I'll be hanging on to these for my last child to use. I recommend them whenever anyone asks "Well, what do you do for math?"

We have used this set with our son who hates Math, and he absolutely loved it. He liked it so much that he wants to learn Math concepts using these books. We particularly liked the fact that they look at problems and study them from very different perspectives, so kids will get the concept one way or another. It really is a great buy!

As a homeschool teacher I've found much better results in the "Immersion" style of teaching most subjects rather than the building block style of teaching in public school. "Immersion" is starting a topic and finishing it before going onto another topic. I've discovered a much more thoroughly learned subject using this method.
We don't need nor do we want (actually avoid) the fluff of games and puzzles for the most part, except as specifically chosen for recreation. "Fluff" takes up precious time... in my opinion.
After learning addition, subtraction, then multiplication, division, as well as time, number lines, estimating, etc., we started on this series. Fractions, Decimals, Percents, Measurement, Metrics, Geometry, Algebra, in that order has been excellent... thus the "Immersion" method at work.
I would continue if they covered more subjects in this manner.
It's very affordable, extremely well written, and exactly what I was looking for. This may not be the style for all teachers and learners. My child is able to work independently and thoroughly grasps the subject matter before moving on, with little to no help.

Steven Rassmussen is a genius, and I'd love to meet this man who understands so deeply how kids learn! I used his materials in the 80's when they were first published, throughout the intervening years until I retired from the classroom, and now, as a tutor, I am using them still. Steven controls the variables in every lesson, just adding one new variable at a time. Kids quickly build confidence in their mathematical thinking because they feel successful page after page. Caution: these materials should not be used by students independent of adult guidance. They absolutely need to hear the "self-talk" that experienced mathematical thinkers use to give themselves feedback and to vocalize the connections among mathematical concepts involved. This kind of elaboration only happens when an adult works with students as they learn. Steven Rassumssen's materials are fabulous whether they are used for whole class instruction or for one-on-one tutoring. They foster the critical thinking we are moving toward with the Common Core Standards as well.
