Getting Started With Connecting Math Concepts Level B
Connecting Math Concepts is a basal math intervention program published by Pearson/VU, originally developed by Virginia Underwood. Level B targets students who have significant gaps in foundational arithmetic and are working at approximately a grades 3–4 level. It covers whole number operations, fractions, decimals, percents, ratios, and introductory algebra through a structured concrete-representational-abstract sequence. If you're a special education teacher or math interventionist, you've probably been handed a stack of CMC workbooks and told to "figure it out." The program itself isn't difficult, but the original implementation has some quirks that trip people up. I'll get into those as we go.
What You Actually Need Before Opening the Book
Level B assumes students can already count forward and backward in groups of 2s, 5s, and 10s, and have a rough sense of place value. If your students can't do that yet, don't start with Level B. Start with Level A, which is essentially a remedial arithmetic refresher with manipulatives built into every lesson. You also need base-ten blocks, fraction tiles, and a set of counters. The program is explicitly designed around manipulatives, and skipping them defeats the purpose of the CRA (Concrete-Representational-Abstract) framework. I've seen people try to run Level B without the blocks because they're "short on time," and it just doesn't work. Students memorize procedures without understanding, then forget them two weeks later. One thing the manual doesn't emphasize enough: you need a working classroom calculator for many of the later lessons in Level B. The CMC series uses calculators as a scaffold, not a crutch. If your building has a calculator policy that prohibits them, you'll hit a wall around Lesson 75 or so when the material shifts into multi-digit operations and decimal arithmetic.
Downloading and Accessing the Materials
The full program is a print-published curriculum sold through Pearson. Most schools purchase the teacher edition with consumable student workbooks. There are also digital resources available through Pearson's Connected Planner platform if your district has a site license. For the student workbooks, you can order directly from Pearson or through educational resellers. The teacher edition contains lesson plans, answer keys, and assessment materials. I'd recommend getting both if your budget allows it. The teacher book has instructional cues that aren't in the student pages, like where students commonly make errors and what to say when they do. If you're an individual practitioner or a small program without a district license, the workbooks show up on Amazon and eBay in used condition. They're durable enough that used copies are usually fine, though the answer keys are only in the teacher edition, which makes grading a pain if you only have the student books.

How a Typical Lesson Unfolds
Each lesson in Level B runs about 30–45 minutes. That's important because the pacing is tight. If you're running this in a pull-out setting with 30-minute blocks, you're going to be rushed. I've done it, and it shows. The lesson structure follows the CRA sequence: Concrete phase: The teacher introduces a concept using physical manipulatives. For example, when teaching fraction addition, students physically combine fraction tiles and see how pieces fit together. This usually takes 5–10 minutes.
Representational phase: Students move to drawings, number lines, or diagrams. They're still not working purely with numbers. This is where most teachers accidentally skip ahead because they think the kids "get it" after the concrete portion. Don't. The representational phase is where the real transfer happens. Abstract phase: Only after students demonstrate accuracy in the first two phases do they work with numerical symbols and standard algorithms. This can take anywhere from one lesson to three lessons depending on the concept. The manual has check-off points built in. After the instruction portion, students complete practice problems in their workbook. The exercises are repetitive by design. That repetition is what builds fluency, not variety.
Where People Go Wrong
I've watched a lot of teachers run Level B, and there are three patterns that come up constantly. First, moving too fast through the concrete phase. This is the biggest one. Students fumble with manipulatives for two minutes, the teacher says "okay, you get it," and moves on. Three lessons later, those same students can't explain why 1/3 + 1/4 doesn't equal 2/7. The concrete phase isn't a warm-up. It's the foundation. Second, grading everything instead of spot-checking. The workbook problems are designed for practice, not assessment. Students should be doing them with teacher guidance during the lesson. Save the formal checking for the periodic assessments built into the program. Grading every page is a time sink that doesn't give you better data.
Third, using Level B materials for students who are significantly below grade level without scaffolding the prerequisites. If a student is working at a kindergarten or first-grade math level, Level B will overwhelm them even though it's supposed to be intervention-level. The jump from basic fact fluency to multi-step operations in Level B is steep. Those students need Level A first, or you need to selectively pull lessons from Level A to fill gaps.
Connecting Math Concepts Level B Specific Pitfalls
Level B has its own idiosyncrasies. One issue I ran into repeatedly: the fraction sections assume students already understand equivalent fractions before introducing addition and subtraction of fractions with unlike denominators. The progression feels natural in the book, but students often stumble because the equivalent fractions concept gets introduced lightly and then immediately reused without reinforcement. My workaround was to create a quick "equivalent fractions warm-up" sheet I used for the first five minutes of class on lessons 40 through 55. It wasn't in the manual, but it prevented a cascade of confusion that would have taken two weeks to untangle otherwise. Another thing: the calculator lessons. The program introduces calculators early and uses them throughout. Some administrators and parents push back on this, thinking it undermines mental math. The research behind CMC is clear that calculators at this level are a scaffold for understanding, not a replacement for computation. But if you're dealing with skeptical stakeholders, having that conversation upfront saves you headaches later.
Assessment and Progress Monitoring
Level B includes periodic assessments at the end of each section. These are short, focused checks on the concepts covered in that block of lessons. They're useful for determining whether a student is ready to move on or needs reteaching. I'd also recommend pairing CMC assessments with a broader progress monitoring tool like DIBELS Math or AIMSweb. The CMC assessments are narrow and specific to the curriculum, which is good for tracking whether students are learning the material. But they won't tell you much about general math growth over time. You need a separate measure for that. The program does not include a placement test. If you're trying to determine whether a student should be in Level B versus Level C, you're looking at informal assessment: review of prerequisite skills, observation of problem-solving approaches, and maybe a few diagnostic worksheets you create or source externally. There's no standardized placement instrument built into the program.
How Long It Takes to Complete
The full Level B curriculum contains roughly 100 lessons. At a rate of three to four lessons per week, that's about 8 to 10 weeks for a student who is attending consistently and making steady progress. Students who struggle with retention or have attendance issues will take longer. I've seen Level B stretch across an entire semester for some students, and that's normal. The material is dense for the population it serves. Level C, which follows Level B, covers more advanced topics including integers, coordinate graphing, and deeper algebraic reasoning. If a student finishes Level B and demonstrates solid mastery on the assessments, moving to Level C is the logical next step. If they're struggling at the end of Level B, don't rush them forward. Solidify the foundation first.
What It Doesn't Do Well
No program is perfect, and CMC Level B has real limitations that you should know about before adopting it. The curriculum is heavily procedural. Students learn to follow steps, which is valuable for building confidence and competence, but the program doesn't do much to develop mathematical reasoning or problem-solving flexibility. If you want students to explain their thinking or approach problems multiple ways, you'll need to supplement with your own questions and activities. The demographic representation in examples and word problems is dated. Some of the contexts feel like they were written in the 1990s. It's not offensive, but it's not engaging for today's students. I've found that swapping out a word problem or two with something more current makes a noticeable difference in attention.
There's limited support for English Language Learners beyond what's in the teacher guide. The language is straightforward, but vocabulary like "numerator," "denominator," "quotient," and "coefficient" needs explicit teaching for DLLs. Plan for that. And here's the blunt part: if a student has a significant cognitive disability that puts them well below a third-grade math level, Level B may still be too advanced. In those cases, consider building a custom curriculum from Level A materials and other foundational resources, or look at programs specifically designed for students with moderate to significant disabilities, like Steps Math or My Math Foundations.
Bottom Line
Connecting Math Concepts Level B is a solid intervention program for students who need structured, sequential math instruction at the elementary level. It works best when you respect the CRA sequence, don't rush through the concrete phase, and supplement where the program is thin. It's not a set-it-and-forget-it curriculum, but for teachers willing to engage with it properly, it produces results. The students who stick with it through Level B typically show measurable gains on standardized math assessments within a semester.
