This book emphasizes problem-solving and computation to build the math reasoning skills necessary for success in higher-level math and math assessments. This book is written to the standards of the National Council of Teachers of Mathematics. The Level B book is a complete curriculum for the first grade level. These highly effective activities take students far beyond drill-and-practice by using step-by-step, discussion-based problem-solving to develop a conceptual bridge between computation and the reasoning required for upper-level math. Activities and units spiral slowly, allowing students to become comfortable with concepts but also challenging them to continue building their math skills. Answers are included in the back of the book. Review: Fantastic math curriculum! - I really love this math book. Well done, Critical Thinking Company! I originally ordered Level A (Grade K) for my kindergartner but he is VERY math oriented by nature and after flipping through it, I didn't think it would challenge him enough. I ordered Level B (Grade 1) and it has been perfect for him. By the way, I kept the Level A book for my younger child to grow into. I love how this book teaches several different approaches for each type of problem. It switches things up often enough to avoid boredom, but also spirals to reinforce learning. The pages are full color and vibrant. There are ~300 worksheets with an answer key in the back. We do 4 worksheets per day, 3 days per week. I do wish it had a lay-flat binding, but that's a minor issue. This is our primary math curriculum that we are using alongside the Classical Conversations Foundations curriculum. I had originally intended to switch to Saxon Math in a few years (around 4th grade), but I'm so happy with the Mathematical Reasoning series that I may stick with it longer. It is an EXCELLENT value for the price. One caution: This book does not provide much in the way of teacher instructions or scripted explanations of new topics, so if you're not comfortable with math basics, you might prefer a more comprehensive curriculum that includes a teacher's guide. However, if you're able to fill in the gaps, this book is absolutely "meaty" enough to serve as your complete math curriculum (not just a supplemental resource). Review: Great core curriculum - My daughter really enjoys this curriculum. I had initially worried it was not appropriate for a full curriculum and was only using it as a supplement but it is the only thing we have stuck with. There are a few pages of teaching instructions in the beginning of the book. Following those instructions coupled with the activities designed to build upon each other I have found works great. The curriculum has a lot of fun easy type pages with some harder still fun pages every several pages or so. Most of the content is grade level and relatively straightforward but fun and unique. The content that is more of a stretch is still fun and my daughter has never complained about this book. They don’t over do it with the algebra like many modern curriculums but there’s plenty of logic and critical thinking included. We love the mind benders especially. Probability is included in a fun age appropriate way. This book is great and we’ll be continuing with the series next year for our homeschool. I wanted to add that even if you do not homeschool, this book is so much fun it would be enjoyable to do with your child as a supplement after school to improve math skills. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #289,024 in Books ( See Top 100 in Books ) #7,691 in Schools & Teaching (Books) #10,073 in Textbooks (Special Features Stores) #60,081 in Children's Books (Books) | | Customer Reviews | 4.7 out of 5 stars 126 Reviews | ## Images ![Mathematical Reasoning Level B Full Curruculum Workbook - Bridging the Gap Between Computation and Math Reasoning (Grade 1) - Image 1](https://m.media-amazon.com/images/I/71yuF76KqEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic math curriculum! *by J***T on February 11, 2019* I really love this math book.

It gradually introduces increasingly complicated concepts in a way that easily frustrated children can stomach. It's colorful, systematic and well organized. I never thought I would love spiral learning, but I am absolutely in love with it. My daughter doesn't bore of it, and there are plenty of pages on every topic. We do skip some of the easier pages, but if she needs a "break" we do them anyway so she can feel a sense of accomplishment. Feeling good about completed work is huge for my 6 year old, and this book does an amazing job of engaging her, teaching her, and helping her feel good about herself. I can't recommend it highly enough. ## Frequently Bought Together - Mathematical Reasoning Level B Workbook - Bridging the Gap Between Computation and Math Reasoning (Grade 1) - Mathematical Reasoning Level A Workbook - Bridging the Gap Between Computation and Math Reasoning (Grade K) - Mathematical Reasoning Level C Workbook: Bridging the Gap Between Computation and Math Reasoning (Grade 2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/85531840-mathematical-reasoning-level-b-full-curruculum-workbook-bridging-the-gap](https://www.desertcart.kr/products/85531840-mathematical-reasoning-level-b-full-curruculum-workbook-bridging-the-gap) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-16*
