Mathematical Reasoning Level E (Grade 4)

We have found the Mathematical Reasoning books to be a really fun way to work on math concepts. The colorful visuals are easy to understand and lend themselves to easy comprehension of the concepts presented.

I love the constant new and review of each topic. It reinforces each new idea.

I purchased this for my 9 year old, it is a nice supplement to our homeschool curriculum. It is nice as a reference point to where the grade levels are, and not so dense he gets bored. Will continue to use this series as the kids go through their education. Thank you!

My family has used Mathematical Reasoning on two different levels this year. We love it. I have a 1st and 3rd grader and the both enjoy Mathematical Reasoning. I bought Mathematical Reasoning Grade 4 to use next year. We live over seas and I have to order in time for people to ship to me or in this case bring to me as they visit. Thanks for all the Timberdoodle greatness!!

We began using Mathematical Reasoning last year with 2nd Grade/Level D, although my daughter was in 3rd grade. She loved Horizons math workbooks, but we were moving on to Teaching Textbooks (Math 3, yay!), and she was lamenting the loss of all the fun colorful pages to fill in. So I ordered Mathematical Reasoning to surprise her, and she was thrilled. I chose to go down a level based on the sample pages, and knowing that the Critical Thinking Co tends to be challenging (which is a good thing).** Mathematical Reasoning Level E (4th grade)is colorful and engaging, and the explanations are easy to understand. It dovetails so well with TT...I like that they use different phrases than TT: "regrouping" instead of "borrow" and "carry," and things like that. Kids need to be able to navigate all the different ways the world approaches math concepts. The book is a nice mix of review and practice, real-world story problems, and games to introduce critical thinking. Once in a while we skip a page if it is overwhelming or repetitive, but it's easy to get through the book at two pages a day. My only complaint is that the spine is flimsy. This is a big, thick, consumable paperback, so a child is going to lean on it, and spill milk on it, and wrinkle the pages, and drop it, and sit on it. Last year we ended up hole-punching the whole thing and putting it in a binder, but this year we are trying something new: I have the child place a similar-sized book directly to the left of the MR book, and the left-hand pages of the MR workbook rest on this extra book while he writes. We'll see how we fare. **Our experience has been that while Teaching Textbooks mirrors standard public school math, Horizons and Critical Thinking Co tend to be about a year ahead, so our curriculum has been as follows: for kindergarten, math is informal; then in first grade we use Horizons K, followed by Horizons 1 in second grade; by third grade, kids are ready for TT3 and Mathematical Reasoning D/2nd; and we ...
