How does Goblins work?

Three simple steps: (1) Share an assignment from thousands of standards-aligned topics using a share code. (2) Students speak and draw their thinking naturally, and Goblins responds with Socratic questioning that sounds just like their teacher. (3) Teachers get real-time formative insights showing what students struggle with and suggestions to inform instruction.

Does Goblins prevent cheating?

What grade level is AQR taught?

This standard is part of the AQR curriculum in Massachusetts Curriculum Framework for Mathematics.

AQR: Model Advanced Quantitative Reasoning [AQR]

Model Advanced Quantitative Reasoning [AQR]

Print

Advanced Quantitative Reasoning is a fourth-year course that applies algebra, geometry, and statistics to real-world contexts. Content spans trigonometric functions, geometric measurement, similarity, and probability decisions. It is designed as an alternative pathway after Algebra 2 or Model Mathematics II.
