RightStart™ Mathematics Levels

RightStart™ Mathematics Level F — Common Questions

RightStart™ Mathematics Level F covers Numeration: squares, square roots, and exponents, long division by two-digit divisors, decimals: operations to the thousandths and dividing by decimals, fractions: unlike denominators, multiplying, and dividing, percents, probability, and combinations, measurement: cubic units and dimensional analysis conversions, coordinate systems: ordered pairs and graphing equations, and geometry: scaling figures and inscribed constructions. Lessons build incrementally and review earlier skills so concepts stick over time.
RightStart™ Mathematics Level F is designed for students working at roughly a 5th Grade level, but placement is based on mastered skills rather than age. The most reliable way to confirm the right starting point is to take the free placement test.
Most students complete RightStart™ Mathematics Level F in one school year at a pace of about four to five lessons per week. You can move faster or slower — the program is self-paced, so spend extra time on tougher topics and move quickly through ones your student already knows.
RightStart™ Mathematics video lessons with Nicole the Math Lady are in development (Starting August 2026). You can take the free placement test now to find the right level and join the waitlist to be the first to know when RightStart™ Mathematics Level F launches.
