Add+VantageMR Fractions empowers educators to use what to guide the teaching of fraction topics?

• A. Diagnostic assessments and learning trajectories
• B. A fixed curriculum for fractions
• C. Only covering whole numbers
• D. Replacing teachers with AI tutoring

Answer: (A)

Using diagnostic assessments and learning trajectories to guide instruction means starting with a clear read on each student's current understanding of fractions and the misconceptions they hold, then organizing instruction along a developmental path that builds toward deeper fraction mastery. Diagnostic assessments reveal gaps and strengths, so tasks can target specific needs, while learning trajectories provide a map of the progression students typically follow as they move from basic ideas like understanding unit fractions and equivalence to applying operations with fractions and solving real-world problems. Add+VantageMR Fractions is designed to support this approach by helping educators diagnose students' fraction knowledge and plan instructional sequences aligned with how students typically develop fraction skills. A fixed curriculum for fractions lacks the flexibility to respond to different students' starting points. Focusing only on whole numbers ignores the topic at hand. Replacing teachers with AI tutoring removes the essential human guidance and adaptive feedback that help students build understanding in fractions.
