Singapore Math Dimensions vs. RightStart Mathematics

Singapore Math Dimensions vs. RightStart Mathematics

The math-curriculum decision tree in issue 02 routed conceptually-strong students past the open-and-go programs and into Singapore Math or RightStart. This week, the side-by-side. Two of the most-respected elementary math programs in the country, graded on the same rubric.

Singapore Math Dimensions K-5. The current US adaptation of the Singapore Ministry of Education's original Primary Mathematics series, published by Singapore Math Inc. in Oregon. Dimensions replaces the older "Primary Mathematics US Edition" as the publisher's recommended scope-and-sequence for new families. A complete level (textbook, workbook, teacher guide, tests) runs $75 to $95 per grade level retrieved May 2026, with the teacher guide the largest line item. Worldview is fully secular. Parent-led, conceptually rigorous, builds the Concrete-Pictorial-Abstract progression the Singapore method is known for.

RightStart Mathematics Levels A-E. Published by Activities for Learning, founded by Joan A. Cotter, PhD. The K-5 sequence built around the AL Abacus, Cotter's modified Asian-style abacus that replaces traditional manipulative kits as the primary tool for developing number sense. The Level A starter kit (manipulatives + lessons + games) runs $235 retrieved May 2026; subsequent levels add $60 to $90 per year for the lessons-and-worksheets pack since the manipulatives carry forward. Worldview is fully secular. Parent-led, scripted, manipulatives-heavy, and built around the thesis that quantity recognition and place value should be developed visually before symbolic notation.

Where each one wins

Singapore Dimensions wins on cost, parent prep load, and continuity into middle school. A family using Dimensions K-5 spends roughly $475 across six years of curriculum, plus a single-purchase manipulative kit ($45 to $80). The sequence also flows directly into Singapore Math's Dimensions 6-8 and then Math in Focus or Art of Problem Solving's Pre-Algebra for high school. The curricular continuity is real and is one of the strongest reasons families pick Dimensions over RightStart at the K decision point.

RightStart wins on early-numeracy depth, kinesthetic learning, and the AL Abacus thesis. The argument for RightStart is that the AL Abacus and the program's manipulatives-first approach build a stronger mental-math foundation than any other elementary program in the secular market. The argument is well-supported by parent reports and by the program's longstanding reputation in the homeschool dyscalculia community. For a kinesthetic learner, for a child who needs to touch the math, or for a family whose primary educator is comfortable with a higher prep load, RightStart is the strongest elementary option in the secular market.

The decision rule

If you want a conceptually rigorous program that fits a 30-minute lesson at moderate parent prep, with a clean continuity path into middle school and high school, the answer is Singapore Math Dimensions. If you want the deepest possible early-numeracy foundation, you are willing to absorb a higher prep load, and you have a child who learns best with manipulatives in hand, the answer is RightStart Mathematics.

A small number of families combine the two. RightStart for K and Level 1 to lock in the early-numeracy thesis, Singapore Dimensions from Level 2 onward for the cost and continuity arguments. That combination is one of the more common "best of both" patterns in the conceptual-math segment.

Tennessee SB 0503 clears the floor, and what changed in the amendment

Tennessee SB 0503 cleared the Senate floor on May 5 by a 22-9 vote, with the companion House bill expected to follow during the week of May 11. The bill creates a $7,200 per-student ESA available to all Tennessee K-12 students, including homeschool families, with universal eligibility phased in over three years.

What changed between committee and floor. The Senate amendment narrowed the homeschool eligibility language to require participating families to register through the state's existing church-related school or independent home-school filing pathway rather than creating a new ESA-specific filing track. Practical effect: homeschool families who already file under one of the two recognized Tennessee pathways become eligible without changing anything operationally. Families currently filing under the umbrella-school-of-religious-affiliation pathway, the most common arrangement in the state, qualify by default.

The amendment also added a scholarship-administration role for the Tennessee Department of Education that shifts the operational model from a Step Up–style nonprofit administrator to a state-agency administrator. This is a meaningful structural difference from the Florida and Arizona models, state-administered ESAs have historically had more rigid expense-approval workflows and tighter audit trails, which is good for accountability and worse for purchasing flexibility.

Watch for the House calendar the week of May 11 and the HSLDA Tennessee tracker for Governor Lee's signature timeline. If signed, Tennessee becomes the eighteenth state with a homeschool-eligible ESA, and the second state in 2026, joining Wyoming's HB 199 signed in March.

Khanmigo free tier, the first two weeks

Khan Academy's free Khanmigo tier for homeschool families opened in late April. Two weeks of usage data from the Every Homeschool reader inbox, summarized:

What is working. The Socratic-tutor mode during Khan Academy's existing math and writing lessons is the highest-value piece of the product. Families are reporting genuine engagement on word problems and on revision feedback for student writing. The chatbot defaults to asking questions rather than providing answers, which is the pedagogical choice the Stanford-evaluated AI tutoring literature favors and which most consumer chatbots do not enforce.

What is not working. The free tier does not include the parent-progress dashboard, which is the piece most homeschool parents would actually want for accountability. Families are reverting to the existing Khan Academy parent dashboard for completion data and treating Khanmigo as a session-by-session tutor rather than a tracked-progress tool.

The honest evaluation. Worth using. Worth not paying for the upgrade tier yet. The product is meaningfully strong for what it is and is not yet strong enough to replace either a curriculum or a parent. Treat it as a free tutoring resource on top of an existing math or writing program, not as a math or writing program itself.

Florida Step Up waitlist, the first movement

Step Up for Students confirmed in early May that the first wave of waitlist clearances is now in progress, with notifications going to families based on the priority order set in Florida Statutes 1002.394. The clearance volume is smaller than in prior years, historically Step Up clears 15 to 25 percent of the initial waitlist by mid-May. This year's first wave is roughly 8 to 10 percent.

What that means for families currently waiting. Plan as if your award will not arrive until the late-July clearance window, not the May or June one. Do not delay curriculum purchases on the assumption a May notification is coming. The historical pattern of "second waitlist clearance in late June" is intact; the magnitude of that clearance is the open question.

What it does not mean. The cap is binding for the first time, and the smaller-than-usual first clearance reflects the cap binding, not a problem with Step Up's administration. Families that have not yet applied for 2026-27 should still apply, the statutory waitlist priority gives application date weight in the queue.

Dispatch

Memoria Press 2026-27 catalog and price hold. Memoria Press, the classical-Christian publisher behind the Latina Christiana and First Form Latin sequences, released its 2026-27 catalog on May 7 with prices held flat for the third consecutive cycle. The notable addition is the Junior Saxons curriculum, a copybook-style addition for K-2, at $24.95.

SEA Homeschoolers conference 2026 dates and venue. The Secular, Eclectic, Academic Homeschoolers conference confirmed July 23-26, 2026 in Cincinnati, Ohio, at the Hyatt Regency Cincinnati. Registration opened May 1 at $399 for the four-day pass. SEA is the largest in-person secular-homeschool conference in the country and is the canonical secular-curriculum vendor hall.

Iowa HF 2612 enacted. Iowa House File 2612, expanding the state's Education Savings Account program to remove income caps in the 2027-28 school year, was signed by Governor Reynolds on May 6. Iowa joins the universal-ESA cohort effective for the 2027-28 application window. The income-cap phase-out schedule had been on a multi-year glide path since the original 2023 enactment; HF 2612 accelerates the timeline by one year.

North Carolina DNPE end-of-year filing window opens. The North Carolina Division of Non-Public Education opened its annual end-of-year reporting window for North Carolina homeschool families on May 1. The window closes June 30. Required: standardized test administration for the school year, on-record. NC families should plan testing dates this month or in early June.
