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.

F.1.MAA

F.1.MAA.1Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers [e.g., the Fibonacci sequence is defined recursively by f(0) = f(1) = 1, f(n+1) = f(n) + f(n−1) for n ≥ 1]F.1.MAA.10Use the relation i^2 = –1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers F.1.MAA.11Find the conjugate of a complex number; use conjugates to find moduli and quotients of complex numbers F.1.MAA.2Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases:F.1.MAA.3Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function F.1.MAA.4Compare properties of two functions each represented in a different way: algebraically, graphically, numerically in tables, or by verbal descriptions (e.g., given a graph of one quadratic function and an algebraic expression for another, determine which has the larger maximum)F.1.MAA.5Write a function that describes a relationship between two quantities:F.1.MAA.6Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms F.1.MAA.7Understand that restricting a trigonometric function to a domain on which it is always increasing or always decreasing allows its inverse to be constructed F.1.MAA.8Use inverse functions to solve trigonometric equations that arise in modeling contexts, evaluate the solutions using technology, and interpret them in terms of the context F.1.MAA.9Know there is a complex number i such that i^2 = –1, and every complex number has the form a + bi with a and b real
