11. Math-U-See
Demme Learning
A complete K-12 math curriculum built on a mastery approach: lessons come with videos, integrated manipulatives, practice worksheets and systematic review pages. Levels run from Primer through Zeta, then Pre-Algebra, Algebra 1 and 2, Geometry, PreCalculus and Calculus. Placement is skill-based rather than by grade, and the site offers placement resources and an accelerated program for filling gaps.
We did not see a price on the pages we read; subscriptions for digital instruction are described on Demme Learning's subscriptions page.
Watch for A full level needs several parts (instruction manual, lesson videos, student workbook, tests and, for Alpha, an Integer Block Kit). Starting at the right level takes a placement step because levels are not tied to grades.
Visit Math-U-See ↗
An online math curriculum for kindergarten through grade 12 built from short video tutorials, interactive questions that mark themselves, worksheets with worked solutions and progress reports. Children can pause, rewind and repeat lessons, and a free trial is offered. The site says it is an approved vendor for several state ESA and EFA programs.
One student is $39.90 a month or $257 for 12 months; the family membership for more than one student is $59.90 a month or $397 for 12 months (as of 2026-10-27). The checkout page offers a 365-day money-back guarantee.
Watch for It is entirely online, so each child needs a device. The refund has to be asked for by email or phone within the 365 days.

33. Teaching Textbooks
Teaching Textbooks
A homeschool math app with a course for each level: Math 3 to 7, Pre-Algebra, Algebra 1, Geometry, Algebra 2 and Pre-Calculus. The course page says each one does the teaching and the grading and gives step-by-step solutions, so students can work on their own. The apps run on computers, tablets and phones and work offline for up to six lessons at a time.
Course prices differ by level and we did not record each one. The large-family plan caps the yearly digital cost at $239.95 for families with 4 to 8 children (as of 2026-10-27).
Watch for It starts at Math 3, so kindergarten to grade 2 need another program. Each course gives 12 months of access plus a 3-month pause, and the free trial covers only the first 15 lessons.

44. Math Mammoth
Math Mammoth
A mastery-oriented curriculum of worktexts for grades K to 8 that stresses conceptual understanding, mental math and number sense. The instruction is written to the student, so the home page calls it open-and-go and nearly self-teaching. Digital downloads and printed books are both sold, and topic-by-topic worktexts can fill gaps or supplement another program.
Grade 3 complete is $42.50 as a digital download, or $21.25 per half-year part (as of 2026-10-27). Printed student books are an extra purchase.
Watch for It stops at grade 8, and the digital version means printing pages yourself or buying printed books separately.

55. Khan Academy
Khan Academy
A nonprofit whose about page describes a free tool for anyone, with courses for kindergarten through high school and early college. Khan Academy Kids is a separate free app for ages 2 to 8 that covers preschool through second grade. A parent can use it as a main course or as extra practice beside another program.
The about page says it is free.
Watch for We did not see a ready-made day-by-day homeschool plan on the page we read, so a parent picks the courses and sets the pace. We read only the about page and have not reviewed the lesson content.

66. Singapore Math
Singapore Math Inc.
The publisher sells Dimensions Math for pre-K to grade 5 (a 6 to 8 collection also exists) and Primary Mathematics in a 2022 edition and other editions.

77. RightStart Mathematics
RightStart Math
A complete elementary and middle-school program that uses visualization of quantities, plays down counting and teaches the facts through strategies and card games. The main tool is the Cotter Abacus. Levels A to H are sold as book bundles, and the site offers a free placement test with no account needed.
Level A to H book bundles are $99.25, or $109.25 with an e-workbook PDF (as of 2026-10-27). The homeschool page mentions a 60-day guarantee.
Watch for It is parent-taught and built around the abacus and games, and supply kits are a separate shop category from the book bundles, so budget for both.

88. Beast Academy
Art of Problem Solving
A challenging elementary program for ages 6 to 13, in five levels.
