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.

The Number System

7.NS.1Extend prior knowledge of operations with positive rational numbers to add and to subtract all rational numbers and represent the sum or difference on a number line.7.NS.1aUnderstand that the additive inverse of a number is its opposite and their sum is equal to zero.7.NS.1bUnderstand that the sum of two rational numbers (p+q) represents a distance from p on the number line equal to |q| where the direction is indicated by the sign of q.7.NS.1cTranslate between the subtraction of rational numbers and addition using the additive inverse, p-q=p+(-q).7.NS.1dDemonstrate that the distance between two rational numbers on the number line is the absolute value of their difference.7.NS.1eApply mathematical properties (e.g., commutative, associative, distributive, or the properties of identity and inverse elements) to add and subtract rational numbers.7.NS.2Extend prior knowledge of operations with positive rational numbers to multiply and to divide all rational numbers.7.NS.2aUnderstand that the multiplicative inverse of a number is its reciprocal and their product is equal to one.7.NS.2bUnderstand sign rules for multiplying rational numbers.7.NS.2cUnderstand sign rules for dividing rational numbers and that a quotient of integers (with a non-zero divisor) is a rational number.7.NS.2dApply mathematical properties (e.g., commutative, associative, distributive, or the properties of identity and inverse elements) to multiply and divide rational numbers.7.NS.2eUnderstand that some rational numbers can be written as integers and all rational numbers can be written as fractions or decimal numbers that terminate or repeat.7.NS.3Apply the concepts of all four operations with rational numbers to solve real-world and mathematical problems.7.NS.4Understand and apply the concepts of comparing and ordering to rational numbers.7.NS.4aInterpret statements using less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), and equal to (=) as relative locations on the number line.7.NS.4bUse concepts of equality and inequality to write and explain real-world and mathematical situations.7.NS.5Extend prior knowledge to translate among multiple representations of rational numbers (fractions, decimal numbers, and percentages). Exclude the conversion of repeating decimal numbers to fractions.
