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.

FUNCTIONS - BUILDING FUNCTIONS

(+)-F.BF.1c Compose functions and state resulting domain.
(+)-F.BF.3c Determine algebraically whether or not a function is even or odd.
(+)-F.BF.4b Verify by composition that one function is the inverse of another.
(+)-F.BF.4c Given the graph or table of an invertible function, determine coordinates of its inverse.
(+)-F.BF.4d Determine an invertible function from a non-invertible function by restricting the domain.
(+)-F.BF.5b Use inverse relationships to solve problems involving logarithms and exponents.
(+)-F.BF.5c Apply the properties of logarithms to rewrite logarithmic expressions in equivalent forms and solve logarithmic equations.

FUNCTIONS - INTERPRETING FUNCTIONS

(+)-F.IF.7d Graph rational functions, identifying zeros and asymptotes when suitable factorizations are available.

FUNCTIONS - TRIGONOMETRIC FUNCTIONS

(+)-F.TF.3 Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosines, and tangent for x, π + x, and 2π – x in terms of their values for x, where x is any real number.
(+)-F.TF.6 Understand that restricting a trigonometric function to a domain on which it is always increasing or always decreasing allows its inverse to be constructed.
(+)-F.TF.7 Solve trigonometric equations: analytically with inverse functions and; graphically with technology and interpret solutions in terms of the context.
(+)-F.TF.9 Prove the sum and difference formulas for sine, cosine, and tangent and use them to solve problems.
