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.

Grade 5

Fractions with unlike denominators are added, subtracted, multiplied, and divided, and fraction and decimal operations connect to place value. Numerical expressions with parentheses, the coordinate plane, and classification of 2D figures are new topics. Volume of rectangular prisms and unit conversions extend measurement work.

5.1Write, explain, and evaluate simple numerical expressions involving the four operations to solve up to two-step problems. Include expressions involving parentheses, brackets, or braces, using commutative, associative, and distributive properties.5.10Add and subtract fractions and mixed numbers with unlike denominators, using fraction equivalence to calculate a sum or difference of fractions or mixed numbers with like denominators.5.11Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers.5.12Apply and extend previous understandings of multiplication to find the product of a fraction times a whole number or a fraction times a fraction.5.13Interpret multiplication as scaling (resizing).5.14Model and solve real-world problems involving multiplication of fractions and mixed numbers using visual fraction models, drawings, or equations to represent the problem.5.15Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.5.16Make a line plot to display a data set of measurements in fractions of a unit (12, 14, 18).5.17Convert among different-sized standard measurement units within a given measurement system and use these conversions in solving multi-step, real-world problems.5.18Identify volume as an attribute of solid figures, and measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised (non-standard) units.5.19Relate volume to the operations of multiplication and addition, and solve real-world and mathematical problems involving volume.5.2Generate two numerical patterns using two given rules and complete an input/output table for the data.5.20Graph points in the first quadrant of the coordinate plane, and interpret coordinate values of points to represent real-world and mathematical problems.5.21Classify triangles according to side length (isosceles, equilateral, scalene) and angle measure (acute, obtuse, right, equiangular).5.22Classify quadrilaterals in a hierarchy based on properties.5.23Explain that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category.5.3Using models and quantitative reasoning, explain that in a multi-digit number, including decimals, a digit in any place represents ten times what it represents in the place to its right and 1/10 of what it represents in the place to its left.5.4Read, write, and compare decimals to thousandths.5.5Use place value understanding to round decimals to thousandths.5.6Fluently multiply multi-digit whole numbers using the standard algorithm.5.7Use strategies based on place value, properties of operations, and/or the relationship between multiplication and division to find whole-number quotients and remainders with up to four-digit dividends and two-digit divisors. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.5.8Add, subtract, multiply, and divide decimals to hundredths using strategies based on place value, properties of operations, and/or the relationships between addition/subtraction and multiplication/division; relate the strategy to a written method, and explain the reasoning used.5.9Model and solve real-word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally, and assess the reasonableness of answers.
