Etymology was a course I took in high school. The study of the origins of words didn't sound to exciting at the time, but I have used what I learned from that class A LOT over the last 25 years. That is why I have my kids do the Word Roots workbooks. The workbook claims to help students "decode" words and that is exactly what it does. The workbooks teach the origin and meaning of prefixes, suffixes, and root parts of words. This helps to expand vocabulary and comprehension. Dare I say that it is also FUN? This is definitely one part of y...(more)

I really like the selection of products offered on the website I ordered three books to help my 5th grader with critical thinking skills After going through the different activities I was impressed with his progress I will definitely be ordering more products from this company

My child enjoys these books. We use the Language Smarts as his curriculum for language arts and supplement the book with other worksheets. The books are easy to use, easy to read and fun to do, with colorful pages and quality information to keep anyone's attention. I have already purchased the same books to use with my younger child. :)

I think it is a great way of teaching children. they fill a big void

I really like the variety of products they offer. We are trying out a computer software this year instead of a book curriculum to make it a little more exciting and interactive. My son is really enjoying the diversity of learning grammar through games.

I LOVE The Critical Thinking Co. - I've purchased several items from them in the past, and have NEVER been disappointed. The materials are always top quality, well written, concise, and easy to use. I've purchased both software and traditional books for my kids to learn logic, analogies, Latin roots, and critical thinking strategies. Unlike some websites, the sample pages for TCTCo. always give you a clear example of what you'll get in your purchase, so there's never any doubt about the product you'll be receiving.

The Critical Thinking Co. products are great! They are wonderful supplements to our curriculum, especially when they need extra practice in math and grammar. My first grader took the Iowa Test and scored on a 3rd and 4th grade level in many of the areas. I believe the Mathematical Reasoning and Language Smarts Workbooks helped her score such high marks. Thank you homeschool buyers co-op for getting us the discounts!

My 4-year-old son is absolutely loving the books in the Pre-K bundle. He asks to do them so often that I went ahead and bought the K/1 bundle already so we won't run out of books before next fall!

I am new to the Co-op, but have used and LOVE the Critical Thinking Co for a couple years. I was so excited to see the coupon and it was SO easy to use. All I had to do was get the code from the Co-op, set up my order, and insert the code at check-out. It was that simple.

Great Stuff. I recommend the material to everyone, homeschool and "regular" school.
