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.

QR.CR.1 Analyze and compare growth and decay using absolute and relative change utilizing real-world contexts.
QR.CR.2 Compare, reason and communicate about proportional and non-proportional models utilizing real-world contexts.
QR.CR.3 Identify, create, and use appropriate models for bivariate data sets (i.e. linear, exponential) to estimate solutions for contextual questions, identify patterns and identify how changing parameters affect the models.

DISCRETE MATHEMATICAL REASONING (DMR)

FINANCIAL REASONING (FR)

QR.FR.1 Identify and research a career goal. Develop a plan and time table for achieving it including educational/training requirements, costs, and other factors (e.g. cost versus savings, income and debt).
QR.FR.2 Understand and apply strategies to monitor income and expenses, plan for spending, implement a diversified investment strategy, and save for future goals.
QR.FR.3 Use models to solve and communicate about contextual financial questions such as credit card debt, installment savings, amortization schedules, mortgage and other loan scenarios.
QR.FR.4 Identify and explain personal and societal consequences of financial decisions.

NUMERICAL REASONING (NR)

QR.NR.1 Represent quantities, using equivalent forms when appropriate, to investigate and describe quantitative and geometric relationships and solve problems in real-world contexts.
QR.NR.2 Reason, model, and communicate with and about percentages (change, incorrect, deceptive, relative and absolute).
QR.NR.3 Understand and compare magnitudes of numbers utilizing real-world context. Understand the importance and impact of unit selection.
QR.NR.4 Use and justify estimation skills, and know why, how, and when to estimate results. Assess and justify the reasonableness of estimations using the context and comparisons to other known values.

STATISTICAL AND PROBABILISTIC REASONING (SPR)

QR.SPR.1 Reason and communicate about the validity of claims based on empirical, theoretical, and subjective probabilities.
