Families ask the same question in a dozen forms: Saxon or Math-U-See, Beast Academy or Math Mammoth, an app or a book, spiral or mastery. There is no single right answer, but there are facts, and every publisher states its own. We put them in one table, read from each publisher’s site, and point to a deeper page for every program. Nothing here ranks one curriculum over another.
Teaching math and coding live since 2020 · 10,000+ students · grades K to 12
In short
Widely used US homeschool math curricula include Saxon (HMH), Beast Academy (Art of Problem Solving), Teaching Textbooks, Math Mammoth and Math-U-See (Demme Learning); schools often use Eureka Math (Great Minds), enVision (Savvas), Go Math (HMH) and Big Ideas Math. They differ in grade range, format (book, video, app) and approach, so choose with each publisher’s placement test and a short trial. Modern Age Coders, which is not connected with any publisher, teaches live online beside whichever one you pick, in a batch or 1-on-1.
Courses that sit beside a curriculum
Each course is taught to the topic your child is on in their own curriculum. The book keeps the sequence; the teacher explains it a second way.

Short answer: they cover overlapping grades in very different ways. Saxon and Math Mammoth are books, Teaching Textbooks is an app, Math-U-See pairs a video with blocks and a workbook, and the school programs come as print editions with a digital platform. The table below puts every program in this guide on one grid, using only words the publisher or the state wrote itself.
| Program | Who publishes or runs it | Grades or ages | Delivery format | Approach, in their own words |
|---|---|---|---|---|
| Saxon Math | Houghton Mifflin Harcourt (HMH) | K to Algebra 2 | Books and kits; online tools such as "iTools digital math manipulatives" | "An incremental approach gives students the time to understand and practice a small concept before adding the next step." |

Curricula we teach alongside
Two groups. Five programs were written for the home and are bought by parents; four are school adoptions that families meet through homework. Each has its own deeper page on this site.
Built for teaching at home. Saxon is the long-running one: HMH says "To master mathematics, students need to build on prior learning", and every lesson’s mixed practice reaches back to earlier work. Our Saxon Math tutor page is for the family whose child does today’s lesson fine but trips over problem 18 of the review set, and it shows how to trace each miss to its lesson of origin.
Beast Academy, from the people behind Art of Problem Solving, is comic-led and puzzle-heavy, with five levels each split into four units. The Beast Academy tutor page suits a child aged roughly 6 to 13 who loves the characters but stalls on the starred problems, and it explains the publisher’s own advice to start "about a level" behind the school grade.
Teaching Textbooks hands almost the whole job to software, which reads problems aloud, grades them and plays a worked solution. Our Teaching Textbooks math help page is written for the moment a student has watched the solution and still cannot say why a step is allowed, usually somewhere in Pre-Algebra or Algebra 1.
Math Mammoth speaks to the child directly in its worktexts and leans hard on mental arithmetic and word problems; it stops before high school, saying "Math Mammoth does not offer algebra 1 or above." The Math Mammoth tutor page helps when a nearly self-teaching book needs a voice, and it covers the publisher’s warning about placing a child too high.
Math-U-See, from Demme Learning, builds each idea with blocks before symbols, through a Build, Write, Say routine and one short video a lesson. Our Math-U-See tutor page is aimed at the levels where blocks give way to algebra, from Delta through Algebra 1, with area-model factoring drawn out step by step.
Adopted by school districts. Eureka Math comes from Great Minds and, in New York, grew out of the EngageNY modules; NYSED says it "discontinued support for the EngageNY.org website on July 7, 2022." The Eureka Math homework help page is for parents who were taught a different method and need the number bond and tape diagram explained before they can help at the table.
enVision, published by Savvas, opens a lesson with an exploration task and only then shows a visual example. Our enVision Math help page walks a K to 8 family through that order, so a child who feels lost in the opening task learns that confusion there is planned.
Go Math! is HMH’s chapter-based K to 6 program, and Into Math is its module-based successor running to Algebra 1. The Go Math homework help page covers both, and its focus is a fixed routine for reading a word problem before any calculation starts.
Big Ideas Math, from Larson Texts’ Big Ideas Learning, is common in middle school and high school classrooms, and its newer programs carry the Math & YOU name. Our Big Ideas Math help page is for grade 6 to Algebra 2 students who can follow the textbook example but cannot spot which method a fresh problem calls for.
Look at where review is placed. HMH says of Saxon that "Cumulative practice and assessments cover ideas from earlier lessons". Great Minds calls Eureka Math squared a "spiraling curriculum" that helps students "build, revisit, and retain" knowledge.
Math-U-See and Math Mammoth sit nearer the other end: a topic is studied until it holds, then the book moves on. Neither style is wrong; a forgetful child may like constant review, a focused one the long chapter.
This separates the programs most. In Teaching Textbooks the app explains; in Math-U-See a video does; in Math Mammoth the page speaks to the child; in Saxon and Beast Academy a parent usually reads alongside.
In the school programs the classroom teacher explains, and homework assumes the lesson happened, which is why parents so often feel locked out of the method.
Comparing options
They are not boxed curricula, though families weigh them against one. Khan Academy is a free self-paced library with a paid AI tutor, RSM an after-school program with its own sequence, and Art of Problem Solving a publisher, online school and campus network.
Khan Academy describes itself as "a small nonprofit funded by donations" and says its library "will always remain 100% free." Its Khanmigo assistant, by Khan’s own account, "guides learners to find the answer themselves", and an account holder must be 18 or older, so a parent signs up on a child’s behalf. Our Khan Academy math vs a live tutor page lays out a criteria table for the family deciding whether a free library is enough or whether a person needs to hear the child reason aloud.
The Russian School of Mathematics runs a K to 12 sequence of its own, with an online branch for grades 2 to 10 and an average class of 12, according to its site. RSM also says "We offer tutoring only as a short-term solution", so it is a program to join rather than help with homework. The RSM alternative page compares the facts in a neutral table and adds two of our own puzzles solved two ways.
Art of Problem Solving goes back to a 1993 book, launched online courses in 2003 "designed for high-performing math students", and runs AoPS Academy at "over 20 locations in 12 states". It also created Beast Academy, whose Level 5 is described as leading into AoPS prealgebra. Our Art of Problem Solving alternative page sets AoPS beside other paths for a strong student and teaches the habit of splitting a hard problem into pieces already known.
Homeschool testing and credit
It depends on the state. Some accept a nationally normed achievement test such as the Stanford 10 as annual evidence; high school credit and diplomas follow state rules that differ widely, so your records matter as much as the curriculum.
| State | What its own text says |
|---|---|
| Virginia (Code 22.1-254.1) | Evidence can be "a composite score in or above the fourth stanine on any nationally normed standardized achievement test" |
| New York (NYSED Q&A) | Probation applies if the composite "is below the thirty-third percentile on national norms" or shows less than a year of growth |
| Washington (RCW 28A.200.010) | A state-approved achievement test "is administered annually to the child by a qualified individual", or a certificated person assesses the child |
| New York, high school | "Credit is given only by schools." NYSED adds that "colleges set their own admissions requirements" |
| Texas (TEA) | "The State of Texas does not award a diploma to students that are home schooled." |
Pearson’s product page lists the Stanford Achievement Test Series, Tenth Edition for "Grades K-12 paper, Grades 3-12 online", co-normed with the OLSAT 8, untimed, with a completion time of "2.25-5.5 hours" for the full battery. Its overview flyer mentions a "2018 Stanford 10 norms update". The Stanford 10 math practice page explains the two math subtests, what a stanine is, and how to pace the test calmly with original problems, never real items.
Computer science is the subject homeschool families ask about most once math is settled, because it is easy to teach well and hard to document. Our homeschool computer science credit page compares New York, Pennsylvania and Texas rules from their own guidance and gives a course record template a stranger could verify.
What this means for your curriculum. Keep its tests: a dated folder of chapter tests, placement results and levels completed feeds a portfolio or transcript later. An achievement test is normed by age grade, not curriculum level. We quote state text but give no legal advice, so confirm this year’s rules with your state education department.
How to choose
Decide who will explain, place your child with the publisher’s own test, then run a short logged trial before buying a full year.
trial = {
"Program A": {"lessons": 10, "minutes": 214, "first_try": 78, "problems": 100, "explained": 5},
"Program B": {"lessons": 10, "minutes": 306, "first_try": 61, "problems": 100, "explained": 9},
}
for name, t in trial.items():
per_lesson = t["minutes"] / t["lessons"]
accuracy = 100 * t["first_try"] / t["problems"]
print(f"{name}: {per_lesson:.1f} min a lesson, {accuracy:.0f}% first try, "
f"explained {t['explained']} of {t['lessons']}")
# Program A: 21.4 min a lesson, 78% first try, explained 5 of 10
# Program B: 30.6 min a lesson, 61% first try, explained 9 of 10| Signal | Program A | Program B | What it suggests |
|---|---|---|---|
| Minutes a lesson | 21.4 | 30.6 | B takes longer; check whether the extra time is thinking or frustration |
| First-try accuracy | 78% | 61% | A feels easier, which can mean good fit or placement that is too low |
| Explain-backs | 5 of 10 | 9 of 10 | B’s child can say why far more often |
On speed and accuracy alone, Program A wins. But the child on Program B explained 9 of 10 problems back, against 5 of 10, so the slower lessons may be building more understanding.
Neither reading is automatically right: a family needing a calm, independent routine may choose A, one heading for algebra may choose B. The log turns a feeling into a reason.
Once a day, pick one problem your child got right and ask, "How did you know to do that?" Count it as explained only if the answer names the idea, such as "I made both fractions into twelfths", not just the steps.
Keep it light: the aim is to see understanding, not to set a trap.
Where a teacher fits
Yes. The curriculum keeps the order and the teacher supplies a second explanation when the first has not landed. Tell us the program, level and lesson; we never ask a family to switch.
A child whose curriculum sits close to their grade, who benefits from hearing classmates reason through similar topics each week.
A homeschooler a level ahead or behind, on a curriculum with its own order, such as Math-U-See’s Greek-letter levels.
A child who reads the lesson, checks their own answers and stays calm. Plenty of families never need outside help, and that is a good sign.
We never complete homework, tests or placement assessments for a student. Each curriculum belongs to its publisher; we teach the mathematics, not their pages.
By grade band
Where each program starts and stops; placement tests decide the actual level.
| Band | Programs whose pages list it |
|---|---|
| K to 2 | Saxon Primary, Beast Academy Level 1 and up, Math Mammoth, Eureka Math, enVision, Go Math!, Big Ideas Math; Math-U-See from Primer by level |
| Grades 3 to 5 | All of the above, plus Teaching Textbooks from Math 3 |
| Grades 6 to 8 | Saxon Courses 1 to 3, Teaching Textbooks Math 6 to Pre-Algebra, Math Mammoth to grade 8, enVision 6 to 8, Into Math, Big Ideas Math, Math-U-See by level |
| Algebra 1 and up | Saxon to Algebra 2, Teaching Textbooks to Pre-Calculus, Math-U-See to Calculus, enVision A|G|A, Into Algebra 1 to Algebra 2, Big Ideas Math to AP |
Common switch points are grade 5 to 6 and Algebra 1; plan a term ahead. Math Mammoth says that "After MM7 or MM8, students can proceed directly to high school math", and Beast Academy points to AoPS prealgebra after Level 5.
A new book uses new words for old ideas; ask what it was called before.
Starting a level lower in a new program is normal, not a step back.

Questions families ask
Start with who will explain each lesson, then check the grade range and place your child with the publisher's own test. A two-week logged trial of your top two choices usually settles it. No program suits every child, so we do not rank them.
A spiral or cumulative program returns to many topics in small doses all year; HMH describes Saxon's practice as covering ideas from earlier lessons. A mastery program stays on one topic until it holds, as Math-U-See and Math Mammoth describe. Both can work; the child's memory and patience decide.
Some families do, since Khan Academy says its library will always be free. It is self-paced, so it works for a child who stays on task alone. Many families pair it with a book or a teacher so someone hears the child reason.
Yes, in our view. Teaching Textbooks, Math Mammoth, Math-U-See and Beast Academy each offer a placement route, and Math Mammoth warns that a child switching from an easier program may be placed too high. Use the publisher's tool, not the school grade.
Math Mammoth says students can go straight to an Algebra 1 course after its grade 7 or 8 books. Beast Academy says Level 5 of its online program prepares a student for AoPS prealgebra. Any Algebra 1 course with its own placement test is also an option.
Yes. Each publisher puts family material online, such as Great Minds' Homework Helpers for Eureka Math, and a teacher can explain the class model to a parent.
Some do. Virginia accepts a fourth stanine or above on a nationally normed test as one option, and New York sets a thirty-third percentile threshold for its testing route. Check your own state's education department for the rules that apply this year.
No. Modern Age Coders is not affiliated with HMH, Art of Problem Solving, Teaching Textbooks, Math Mammoth, Demme Learning, Great Minds, Savvas, Big Ideas Learning, Khan Academy or RSM. Their names and trademarks belong to them.
Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.
Yes. The first class is free and no card details are needed. Tell us your curriculum, level and lesson so the teacher can prepare.
