To be fair we used Horizons with my first child and it worked great. I don't know if has been changed in the last 3 years but I ordered it again for my 2nd (concrete sequential) child and it didn't work for her. I will explain why: #1. The work book jumps from subject to subject without a progressive sequential build up of the important basic skills such as adding/multiplying single digit numbers. The first multiplication skills required are far beyond a child that has never been taught or practiced. I had to rework the entire program & write up manipulative skill worksheets to teach her those. I am disappointed that these workbooks missed those foundation skills.
I love the Horizons Math Workbooks! They are very colorful and teach concepts way earlier than they do in public school. For example, starting in second grade, they have kids solving simple algebra equations. We will continue to use these as long as we homeschool. : )
IT WORKS! What else can I say. My 3rd grade dtr (that hates math) is a MATH WHIZ! It is so funny to hear her chat with friends and listen to her say how much she hates math and yet she can easily pop off multiplication facts and she is so proud of her grasp of Roman Numerals. Not to mention her grasp of pre-algebra concepts! I am devastated that we lose Horizons Math after 5th grade. I am already on the prowl for something that can hold her interest like these books do. LOVE LOVE LOVE Horizons Math!
We are using this book for our daughter who is now homeschooled after a struggle in the public school setting. We appreciate this curriculum for the nice balance of pictures/color with work/numbers. It would be a nice choice for a student who is distracted by too many manipulatives or activity on a page, but would be overwhelmed or bored with a black and white page of problems. The lessons are short enough to keep the child's attention but long enough to practice multiple skills. It has great spriraling review and variety of skills and exercises daily. I have not used the teacher's manual except for the answers, and suggest only purschasing Part 2 of the Teacher's Manual, which has the answers. Part 1 has the lessons plans.
