Nubric Overview

Nubric is a web-based assessment and content creation platform designed to help educators create interactive math quizzes and practice activities. It combines structured quiz authoring, random variable generation, and AI-assisted question creation to support scalable and flexible math assessment workflows. Nubric can be used by individual teachers or through organizations that bring together educators from the same academic institution. There are integrations available for the following LMSs:

• Google Classroom (with and without the add-on).
• Blackboard (via LTI 1.3).
• Canvas (via LTI 1.3).
• D2L/Brightspace (via LTI 1.3).

What It Is

Nubric is an online tool that enables teachers to create, manage, and share interactive math quizzes. It provides structured quiz authoring capabilities, including support for dynamic question generation using random variables and advanced logic.

The platform is designed to integrate into common educational environments, such as Google Classroom and other learning management systems (LMS), allowing teachers to embed quizzes into their existing workflows.

Nubric offers Free and PRO plans for individual teachers. Academic institutions can also use PRO organizations to bring together their educators and centrally manage their access. Access to a PRO organization is controlled: teachers must receive and accept an invitation before becoming members.

Nubric focuses on making math assessment creation efficient, reusable, and adaptable to different classroom contexts.

Why It Matters

Creating math assessments often requires repetitive formatting, manual content adaptation, and limited reusability of exercises. Teachers frequently rely on static materials that cannot be easily customized or regenerated.

Nubric addresses these challenges by:

• Enabling reusable quiz structures.
• Supporting dynamic question generation through random variables.
• Allowing public sharing and reuse of quizzes through a content bank.
• Integrating directly into LMS environments to reduce friction.

This improves teacher productivity, supports differentiated learning, and enables scalable assessment strategies.

How It Works

Nubric follows a structured workflow that guides you from quiz creation to student practice. Each stage is supported by specific features and tools.

Stage 1: Quiz Creation

Teachers create a quiz as the container for questions. Each quiz can include multiple question types, including dynamic questions powered by random variables.

• Exploring the My Quizzes page.
• Using the Public Content Bank.
• How Nubric questions work.

Stage 2: Question Authoring

Within a quiz, teachers create questions using structured inputs. Questions may include:

• Static content.
• Random variables with conditions.
• AI-assisted generation.
• Automatic evaluation rules.

Stage 3: Delivery and Practice

Quizzes can be assigned or shared with students. They can be:

• Assigned through an LMS (e.g., Google Classroom).
• Shared publicly.
• Used in student-only mode for independent practice.

Key Rules or Behaviours

• Questions must belong to a quiz; they cannot exist independently.
• Random variables are generated per attempt, ensuring variation across students.
• Public quizzes can be reused and edited by other teachers.
• Some features (such as LMS integration) depend on proper authorization and configuration.
• The features and usage limits available to teachers depend on their Nubric plan.
• Joining a PRO organization requires an invitation from one of its Admins.

Examples

Example 1: Automatic assessment

Nubric evaluates answers based on mathematical equivalence, not just exact text matching. For example, the expressions 2(x + 1) and 2x + 2 are considered equivalent and can both be accepted as correct answers.

This allows teachers to focus on mathematical correctness without having to manually define all possible valid forms.

Example 2: Additional properties

In some cases, not only the value of an answer matters, but also its form. For example, when teaching algebraic manipulation, you may want students to provide a factorized expression rather than an expanded one.

Nubric allows you to enforce these constraints and define partially correct answers with specific feedback.

Example 3: Random parameters

Nubric allows you to generate dynamic questions by defining random variables and expressions. For example, a question can include parameters that change for each attempt, ensuring that each student receives a different version.

All generated variations are evaluated using the same logic, making the question reusable and scalable.

Example 4: Units of measurement

Nubric supports units of measurement, making it suitable for subjects beyond mathematics, such as physics or chemistry. For example, a time value such as 2h 20min can also be correctly expressed as 140min or 2.33h.

The system automatically evaluates equivalent units, ensuring accurate grading across different representations.

Example 5: AI-generated question

Nubric includes AI-assisted question generation to help create draft content quickly.

A teacher can provide a structured prompt, and the system generates a question that includes:

• A problem statement.
• A correct answer.
• Basic evaluation settings.

The generated content can then be reviewed and refined before use.

Common Misunderstandings

Nubric is only a quiz delivery tool

It is both a quiz authoring and delivery platform, including dynamic generation and logic control.

Random variables can only take on simple intervals

Nubric supports conditional logic and advanced expressions for more complex generation scenarios.
