Is Goblins free for teachers?

Yes. Goblins offers a generous free tier that includes 1 live feedback assignment per week, insights on student mastery and replays, and the ability to upload your own content. The Max plan adds unlimited assignments, superadaptive mode, grade exports, standards growth reports, and SSO/LMS integration, with per-student pricing for schools and districts.

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?

Yes. Goblins uses a purpose-trained AI model that evaluates cheating signals in real time. It can detect when students are copying answers, using external tools inappropriately, or not genuinely working through problems. Copy-pasting answers is also blocked.

Can I use my own voice with Goblins?

Yes. Teachers can record their voice and take a selfie to create a custom 3D avatar in about 30 seconds. Students then hear help in their own teacher's voice and see a familiar face, making the experience more personal and effective.

What math levels does Goblins cover?

Goblins covers math from Grade 5 through AP Calculus, including thousands of standards-aligned topics. Teachers can also upload their own content for custom assignments at any level.

Is Goblins FERPA compliant?

Yes. Goblins is FERPA and state compliant. Student data privacy and security are a top priority.

Does Goblins support English Language Learners?

Yes. Goblins supports 30+ languages so teachers don't have to translate every worksheet. It is especially helpful for ELL students who need accessible math instruction in their native language.

HS.F

Conceptual Category Functions

HS.F.1Understand properties and key features of functions and the different ways functions can be represented. (MP.2, MP.4, MP.7)HS.F.10Understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents with the use of technology. (MP.1, MP.7)HS.F.11Distinguish between situations that can be modeled with linear functions and with exponential functions. (MP.3, MP.8)HS.F.12Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table). (MP.7, MP.8)HS.F.13Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function. (MP.7, MP.8)HS.F.14Interpret the parameters in a linear or exponential function in terms of a context. (MP.1, MP.2)HS.F.15(+)Understand the relationship of radian measure of an angle to its arc length. (MP.1, MP.6)HS.F.16(+)Understand and use the unit circle. (MP.7, MP.8)HS.F.17(+)Choose trigonometric functions to model periodic phenomena with specified period, midline and amplitude. (MP.4, MP.5, MP.6)HS.F.18(+)Understand that restricting a trigonometric function to a domain on which it is always increasing or always decreasing allows its inverse to be constructed. (MP.2, MP.3)HS.F.19(+)Use inverse functions to solve trigonometric equations that arise in modeling contexts; evaluate the solutions using technology and interpret them in terms of the context. (MP.4, MP.5)HS.F.2Recognize that arithmetic and geometric sequences are functions, sometimes defined recursively, whose domain is a subset of the integers. (MP.7, MP.8)HS.F.20(+)Proving identities and formulas within the context of trigonometry. (MP.3, MP.7)HS.F.3Understand average rate of change of a function over an interval. (MP.2, MP.4)HS.F.4Graph functions expressed symbolically and show key features of the graph, with and without using technology (computer, graphing calculator). (MP.4, MP.5)HS.F.5Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function. (MP.3, MP.6)HS.F.6Write a function that describes a relationship between two quantities. (MP.4, MP.7)HS.F.7Use arithmetic and geometric sequences to model situations and scenarios. (MP.4, MP.8)HS.F.8Understand the effects of transformations on the graph of a function. (MP.3, MP.5)HS.F.9Find inverse functions. (MP.2, MP.6)
