Where they match

How each one plays by grade

Dimensions Math (Singapore Math)

Grades PreK-8

Parent-taught in PK-2 with the heaviest prep of the line, semi-independent by grades 4 and 5, and expected to be independent from grade 6 on. Homeschool parent support thins at grade 6 and again at 7 and 8, so plan an exit or a tutor there.

RightStart Mathematics

Grades K-8

Levels A through D are the most parent-intensive and the ones most families rave about. Levels G and H are written to the student and turn into geometry-heavy courses, so independence jumps there. Owners report standardized scores dipping in grades 1 through 3 before recovering, since the test order does not match the lesson order. Plan on a two-year commitment; transferring in or out mid-stream is where most families struggle.

Who RightStart Mathematics fits

Works in a house with one or two younger kids where a parent can sit down for half an hour a day, and it's a rescue for a child who's shut down on a workbook program. Families juggling several school-age kids, anyone who needs math their child can do alone, and families working with a diagnosed math learning disability won't get what they need here.
