Recommended Ages
Desmos shines from roughly 6th grade through college-level math, though some visual tools can be introduced earlier as enrichment.

6th Grade through College Level (most common in secondary math)

Desmos is a free, browser-based graphing calculator and activity platform that helps students visualize and explore math from middle school through college. Instead of pushing buttons on a handheld calculator, learners type expressions directly and instantly see graphs, tables, and sliders update in real time. For homeschool families, Desmos can make abstract ideas-like functions, inequalities, and transformations-much more concrete, and its interactive classroom activities (many of which can be run with a single learner) encourage students to make predictions, test ideas, and revise their thinking. Desmos is not a full curriculum, but it pairs beautifully with many middle and high school math programs as a visualization and exploration tool.

Desmos is a great fit for students in middle school, high school, or early college who are working with algebra, geometry, trigonometry, or calculus and who benefit from visual representations and interactive exploration.

Pros

Powerful and free; excellent for visualizing complex ideas; widely used and supported; and flexible enough to support everything from quick checks to deep explorations.

Cons

Cons: Requires internet or a supported app; can feel intimidating for beginners; and does not by itself provide a complete math course.

Because Desmos is free to use, families typically do not need ESA, charter, or other government funding to access it. In some cases, districts adopt Desmos as part of their core curriculum partners.

The core Desmos graphing tools and many activities are free. Any additional paid products or curriculum integrations are arranged through Desmos or partner organizations, and families should check those providers for details.

What kids will learn

Desmos Mission

Desmos's mission is to help every student learn math and love learning math, by providing tools and activities that make mathematical ideas more visual, interactive, and collaborative.

Desmos Story

From its beginnings as an online graphing calculator, Desmos has expanded into a full activity platform where teachers and curriculum writers can build interactive lessons. It has been adopted by districts, curriculum providers, and teachers around the world, becoming a staple in many secondary math classrooms and homeschools.

About Modular Learning

FAQ: Additional Details about Desmos

In a typical Desmos session, a student types an equation, watches the graph appear instantly, and then plays with sliders or additional expressions to see how the picture changes. In activity mode, they respond to prompts, sketch ideas, and compare different representations of the same situation.

To use Desmos, visit the website or open the app, choose the graphing calculator or an activity, and begin entering expressions or working through prompts. Saved work requires a free account, but many features can be explored without logging in.

Adults often act as facilitators-choosing tasks, asking probing questions, and helping students connect what they see in Desmos to their textbook or problem sets. Independent teens may also explore Desmos on their own as a study aid.

Students should be comfortable with basic algebraic notation and using a keyboard or touch screen to enter expressions. Adults using the activity platform will benefit from exploring tutorials or sample lessons before building their own.

Desmos itself does not adapt content automatically, but it gives educators and families flexible tools. Learners can adjust sliders, test different parameters, and explore at their own pace, while adults can choose or design activities that match current topics and the level of scaffolding needed.

For some learners with ADHD, Desmos's interactive visuals and immediate feedback can make lessons more engaging, while others may find it tempting to experiment endlessly without focusing on a particular goal. Clear tasks and time boundaries help.

Desmos was not designed specifically for autistic learners, but some may appreciate the predictable rules and short, repeatable rounds of play. Others may find certain visuals, sounds, or time pressures overstimulating, so it helps to preview games and keep sessions short at first.

Desmos can offer powerful visual support for some concepts related to dyscalculia, like number lines and function relationships, but it is not a structured intervention. Learners with significant math learning differences will usually need more targeted, step-by-step programs.

Desmos reduces some reading load by representing many ideas visually, but still includes written prompts and labels. It can be a helpful supplement for students with dyslexia when combined with read-aloud support and explicit reading instruction elsewhere.

Desmos includes bright colors and simple animations, but intensity varies by game. Families of kids with sensory processing differences may want to stick to calmer titles and lower device volume if needed.

Desmos is a flexible, informal practice site rather than a therapeutic intervention. It can be paired with many accommodations, such as working in short bursts, playing alongside an adult, or using it only after more structured instruction from another program.

Many gifted learners appreciate Desmos's depth and flexibility, using it to investigate patterns, test conjectures, and explore advanced topics earlier than they might in a traditional course.

For twice-exceptional learners, Desmos can offer a fun way to practice math skills without as much pressure as a formal lesson. Adults can adjust expectations and time limits to fit the learner's energy and focus on a given day.

Profoundly gifted students and math enthusiasts can use Desmos as a playground for creative mathematics-building complex graphs, animations, and explorations that go far beyond typical course requirements.

Because most interaction in Desmos involves clicking or tapping rather than writing, it can be easier for kids with dysgraphia than traditional paper drills. It does not, however, address handwriting or written expression directly.

The core Desmos graphing calculator and many activities are free to use. Any paid offerings or partnerships are handled directly through Desmos or curriculum providers, and families should consult those sources for specific terms.

Desmos is not designed as a stand-alone curriculum for beginners and can feel intimidating if students have little algebraic background. Families who prefer paper-only math or whose devices struggle with online tools may also find it harder to use consistently.

Traditional handheld graphing calculators, GeoGebra, and other dynamic geometry or graphing tools can play similar roles. For full curricula, many programs now integrate Desmos-style activities or partner directly with Desmos.

Desmos regularly updates its calculators and activity platform, adding features, improving accessibility, and expanding its library of teacher-created lessons.

Use Desmos to explore and visualize concepts you've already introduced, rather than as the very first exposure. Ask students to predict what will happen before they move a slider or add a term, then talk through the results together.

Meet Desmos

Desmos was founded by math educator and entrepreneur Eli Luberoff, who wanted to create a graphing calculator that was both powerful and accessible to any student with a web browser. Over time, the Desmos team has grown to include teachers, engineers, and designers focused on building rich, interactive math experiences. A fun fact: Desmos's graphing calculator is approved for use on several major standardized exams, which means many students now meet it in class before seeing it on test day.
