Math in Focus

Math in Focus is Houghton Mifflin Harcourt's American adaptation of the Singapore My Pals Are Here series, and it is the version of Singapore math that has made the most serious peace with American homeschool schedules and American public-school scope-and-sequence expectations.

Who the publisher is

Math in Focus is published by Houghton Mifflin Harcourt, the large American educational publisher, as its US adaptation of Singapore's My Pals Are Here mathematics series. The original My Pals Are Here is published by Marshall Cavendish and is among the primary mathematics programs used in Singaporean schools; Singapore's consistently high international math rankings (TIMSS, PISA) drove American interest in adopting Singapore-style curriculum, and Math in Focus is HMH's answer for the American K-8 market.

The program exists in two primary contexts. In public schools, Math in Focus is a classroom-adopted textbook series that districts select when they want Singapore pedagogy aligned to US state standards. In homeschooling, it is one of three commonly cited Singapore math options, the others being Singapore Math Inc.'s Primary Mathematics (Standards Edition and 2022 Edition) and Dimensions Math, also from Singapore Math Inc. Homeschoolers choose Math in Focus when they want Singapore pedagogy with fuller US standards alignment, more polished American-classroom-style layout, and a more developed teacher's edition than Primary Mathematics provides.

The curriculum covers kindergarten through eighth grade, with elementary books K-5 and three middle-school courses (Math in Focus Course 1, Course 2, and Course 3) corresponding roughly to grades 6, 7, and 8. There is no Math in Focus high-school course; families who use Math in Focus typically transition to Saxon Algebra, Art of Problem Solving, a traditional Algebra textbook, or the Singapore Math Inc. high-school sequences at the secondary level. Cathy Duffy's review treats Math in Focus as a strong homeschool option for families committed to Singapore pedagogy.

The core pedagogy

Math in Focus follows the concrete-pictorial-abstract (CPA) progression that defines Singapore mathematics pedagogy. Every new concept is introduced first with concrete manipulatives or physical objects, then with pictures and diagrams, and finally in abstract symbolic form. The sequencing is designed so that students build genuine conceptual understanding before manipulating symbols, which is the central Singapore argument about why American students often struggle with math at the abstract level.

Scope and sequence moves more slowly than traditional American math programs in the early years and more deeply. A third-grade Math in Focus student will spend substantial time on place value, multiplication, and the bar-model approach to word problems before moving to division or fractions; the same student in a more traditional spiral curriculum might have covered more topics more superficially. The Singapore tradeoff is breadth for depth, and Math in Focus preserves that tradeoff while aligning the overall scope to US standards so that a student finishing fifth grade has covered what US fifth-grade standards expect.

Signature mechanics: (1) Bar-model problem solving. Singapore's distinctive method for representing word problems visually as rectangles whose lengths represent quantities. This is the program's most transferable skill, and students who learn it well often outperform peers on word problems for years afterward. (2) Number bonds, a visual representation of how numbers decompose into parts, introduced early and used throughout. (3) Mental math emphasis, students are taught multiple mental math strategies for computation, not merely one algorithm. (4) Structured teacher's edition, the US-adapted teacher's edition is substantive, with detailed lesson plans, common student errors, and prompts for classroom (or one-on-one homeschool) use.

A day in the life

A fourth-grader using Math in Focus typically has math scheduled five days a week, forty-five to sixty minutes per session. A Tuesday session opens with a short mental math warm-up (five minutes), skip counting, number bond practice, or a quick bar-model review. The parent then opens the teacher's edition and walks through the current lesson's concept. Lesson structure in Math in Focus is notably explicit about the concrete-pictorial-abstract sequence: the lesson might introduce area through a hands-on activity (arranging tiles in a rectangle), move to pictures (grid drawings in the textbook), and then to the abstract formula (length times width). The student completes the guided practice in the textbook with the parent, then moves to independent practice in the workbook. Total session: forty-five to sixty minutes; three to four workbook pages completed.

The parent's role is substantial but structured. A parent who has not studied Singapore math needs the teacher's edition, not optional, and needs to read it in advance of each lesson. Unlike Saxon Math, which a competent fourth-grader can self-teach after initial parent instruction, Math in Focus assumes an adult who is teaching the lesson. This is the primary homeschool tradeoff: stronger conceptual content at higher parent-preparation cost. For families where the parent wants to be actively involved in math instruction, this is a feature. For families where the parent wants math to be more hands-off, Saxon or a video-taught program is a better fit.

What they do exceptionally well

Conceptual depth. Students who complete the full Math in Focus elementary sequence genuinely understand what mathematics is doing, not just how to execute procedures. The bar-model approach to word problems, the mental-math emphasis, and the concrete-pictorial-abstract progression produce students who can talk about mathematical reasoning, not merely solve problems. This is the durable advantage Singapore math has over spiral drill programs.

US standards alignment. Among Singapore math options, Math in Focus is the most fully aligned to American public-school scope-and-sequence expectations. Families whose children may at some point move between homeschool and public or private school benefit from this alignment; transitions are smoother than they are with Primary Mathematics in its pure Singapore standards edition.

Polish. The US adaptation by HMH is well-designed. Textbook pages are visually clean, illustrations support the concrete-pictorial progression, and the overall production matches or exceeds what public-school districts expect from a major publisher's textbook series. Students who have bounced off the more utilitarian design of Primary Mathematics often engage more consistently with Math in Focus.

What they do poorly

Parent preparation load. The teacher's edition is essential, and a parent who tries to run Math in Focus without reading ahead will find the concrete-pictorial-abstract sequence awkward. This is particularly true for parents who did not themselves learn math this way, which is most American parents. The program is not open-and-go.

Price stack. Math in Focus pricing reflects its origin as a textbook series for school districts. A full grade-level homeschool kit, student book A and B, workbook A and B, teacher's edition, runs meaningfully more than Saxon Math or Singapore Math Inc.'s Primary Mathematics at the same grade. Digital resources add further. For a family on a tight budget, Math in Focus is not the cheapest way into Singapore pedagogy.

High-school gap. The sequence ends with Course 3 (roughly eighth grade). Families who want to continue in an HMH-published Singapore-tradition high-school sequence do not have one; they must transition to another publisher for Algebra I and beyond, and the transition introduces the usual break in continuity.

Who it fits / who it doesn't

• Pick Math in Focus if: you want Singapore pedagogy with US standards alignment and polished production; you are willing to invest parent time in preparing and teaching lessons; you are teaching K-8 math and will transition out for high school; you value conceptual depth over procedural breadth; you have a child who benefits from visual representation (bar models, pictures, manipulatives).

• Skip Math in Focus if: you want hands-off math where the parent grades and does not teach; you are price-sensitive and want the cheapest Singapore option; you need a K-12 math progression from one publisher; you prefer spiral review over mastery-deep sequencing; your student struggles with the concrete-pictorial progression and needs a more linear procedural approach.

Cost honest assessment

As of April 2026, Math in Focus pricing varies by grade and retailer. A typical full homeschool kit for one grade, student books A and B, workbook A and B, and teacher's edition, runs approximately $180-$280 per Houghton Mifflin Harcourt's homeschool pricing and from major retailers. Individual components can be purchased separately at lower cost for families buying only what they need.

Compared to Singapore Math Inc.'s Primary Mathematics 2022 Edition (roughly $80-$150 for a grade kit), Dimensions Math (roughly $90-$160 for a grade kit), Saxon Math (roughly $100-$180 for a grade kit), and Beast Academy (roughly $100-$150 for a grade-level set), Math in Focus sits in the upper end of elementary math pricing. Families who want Singapore pedagogy at a lower price point typically choose Singapore Math Inc.'s Primary Mathematics; families who want a more polished US-adapted version and are willing to pay for it choose Math in Focus.

An all-in annual math budget for one elementary student using Math in Focus: $180-$280. For two elementary students at different grades: $360-$550 without ecosystem discounts.

ESA eligibility notes

Math in Focus is approved on most state ESA marketplaces and is commonly purchased through Arizona's ClassWallet, Florida's MyScholarShop, Utah Fits All, and Arkansas's LEARNS Act marketplace as of April 2026. Because the content is secular, religious-materials restrictions do not apply. Houghton Mifflin Harcourt's scale as a publisher means the products are well-stocked on state marketplaces and approval workflows are typically smooth. Digital components may be treated differently than print textbooks under some state rules; families using ESA funds for the digital platform should verify eligibility before ordering.

Alternatives

• Singapore Math Inc. Primary Mathematics or Dimensions Math, a family would pick Primary Mathematics or Dimensions over Math in Focus because they are cheaper, closer to the original Singapore scope and sequence, and preferred by families who want Singapore pedagogy without US standards adaptation.
• Saxon Math, a family would pick Saxon over Math in Focus because Saxon's incremental spiral approach produces strong computational fluency with less parent teaching load, at the cost of less conceptual depth and fewer visual representations.
• Beast Academy (Art of Problem Solving), a family would pick Beast Academy because its comic-book presentation and problem-solving orientation appeal to mathematically talented students who thrive on challenge over drill.

How we verified this
