Technology in the math classroom Archives

If you’ve been in the math world for a while, you know the name Desmos. It’s synonymous with free dynamic math tools.

And lately, you’ve probably also been hearing about Amplify and Desmos together. But other publishers also say they have Desmos, so what’s the deal?

Let’s clear it up.

The most important thing to know is that, back in 2022, the original Desmos split into two separate parts. Think of them like a calculators and other tools part and a classroom activities and curriculum part.

The tools part: Desmos Studio

This is the Desmos you first fell in love with.

What it is: Desmos Studio is the name of the company that builds and maintains the powerful, free Desmos calculators. This is an independent Public Benefit Corporation, and can be found at www.desmos.com. That team builds and maintains a collection of free math tools:

Six colorful icons represent types of calculators—Graphing, Scientific, Four Function, Matrix, Geometry, and 3D—each featuring a distinct mathematical symbol. Perfect for desmos math enthusiasts and edtech companies alike.

What it’s for: This is your go-to for exploration, demonstrations, and “What if I change this?” moments. It’s the blank canvas you use on your smartboard or the tool your students use for homework.

The bottom line: The calculators are run by an independent company called Desmos Studio PBC. You can find their tools for free at their website, desmos.com; on state tests; and in curriculum programs (including ours).

A Desmos graphing calculator displays the quadratic function y = 2x^2 - 3, showing a parabola opening upwards with its vertex at (0, -3)—a great example of how edtech companies like Desmos Math enhance classroom learning.

The lessons: Amplify Classroom & Amplify Desmos Math

What it is: In 2022, Amplify acquired the Desmos instructional platform (then called Desmos Classroom, now called Amplify Classroom) as well as their math curriculum for grades 6–8 and the teams that built those resources. We had already been working on our own math curriculum, decided to combine forces with the Desmos curriculum team, and created Amplify Desmos Math, now available for grades K–12.

When other publishers may talk about having “Desmos,” what they mean is they license the calculators and Geometry tool from Desmos Studio.

What it’s for: Amplify has these tools, too, but we also have the Activity Builder, which integrates these tools much more deeply than is possible with other Desmos Studio partnerships. We take this powerful Desmos technology and layer instruction, student collaboration, and dynamic teaching tools on top, creating classrooms that buzz with excitement and learning.

What’s available for free:

The “Desmos activities” platform (you might know it from teacher.desmos.com), now Amplify Classroom. This is where you can find hundreds of free lessons and activities. You can also use the Activity Builder tool to create your own custom activities from scratch.
The beloved, pre-built “Activity Builder” activities like “Marbleslides” and more are still available for free on Amplify Classroom.

The bottom line: Educators can still use the vast library of free activities and build their own on Amplify Classroom. This is not changing.

A grid-based puzzle inspired by Desmos Math, where you guide a green ball to a yellow star by entering coordinates in the answer box, offers an engaging approach popular among edtech companies.

The core curriculum: Amplify Desmos Math

This is the new, comprehensive curriculum available to districts and schools.

What it is: This is a full core math curriculum for grades K–12 that Amplify has built in collaboration with the Desmos curriculum team that joined us a few years ago. It uses the Desmos instructional philosophy and tools as its backbone, but it’s much more than a collection of activities.

What it’s for: This program is designed to be your primary, day-to-day curriculum. It includes a complete, standards-aligned scope and sequence, print materials, digital lessons (with activities enhanced and aligned to standards), assessments, intervention resources, and personalized practice.

The bottom line: If you want a complete curriculum in which every lesson is built on polished Desmos-style activities, you want Amplify Desmos Math K–12. This core curriculum is offered exclusively by Amplify.

Two-page educational lesson plan titled "Can You Dig It?" covering positive and negative numbers, with objectives, vocabulary, standards, and a step-by-step activity inspired by the Desmos math curriculum.

A student writes in a notebook at a desk with a laptop, as her awesome teacher stands beside her. Both appear engaged in conversation about her academic struggles during ELA class.

Many of today’s math classrooms are facing a perfect storm: declining scores, widening learning gaps, and growing pressure on teachers to deliver solutions. According to the National Assessment of Educational Progress, students are experiencing the steepest drop in math scores since 1990. EdWeek Research Center reports that a persistent gap between educational theory and day-to-day practice is putting added stress on teachers, often leaving them to navigate complex pedagogical demands without adequate support.

So how can we provide both students and teachers with the tools they need to succeed? How can math assessments and math intervention programs provide real help and drive student progress—without piling on more work?

One promising answer lies in rethinking how we assess what students know.

Rethinking the role of math assessments

Traditional assessments tend to focus on correctness alone. Did the student get it right or wrong? How many points did they earn?

But this binary approach misses a lot. A skipped question could mean a tech hiccup or a moment of confusion—not a lack of understanding. A wrong answer might come at the end of otherwise solid problem-solving.

An asset-based assessment approach shifts the focus from mistakes to meaning. It looks beyond outcomes to understanding how students think—their strategies, reasoning, and partial understandings. And when teachers can see that thinking, they gain far more useful data to guide instruction and inform their math intervention program.

This approach doesn’t lower expectations—it raises the quality of insight and gives struggling students (and really all students) a better shot at meeting standards with instruction that’s tailored to their actual needs.

Honoring students’ thinking and teachers’ time

Every student thinks differently. Asset-based assessments help reveal individual thinking, often through short-answer or open-response formats that ask students to explain how they solved a problem.

But this shift isn’t just for students. Teachers can benefit enormously when assessments are designed to surface trends in student thinking. If 30% of a class misinterprets the same concept, that result reveals a teaching opportunity. Rather than reteach an entire unit, teachers can adjust with focused, targeted support. That means less time spent diagnosing, and more time actually helping.

And when technology in the math classroom makes this data easy to collect, analyze, and act on, teachers get a level of consistent insight that is not only helpful, but actionable.

From student performance to student performance + thinking

The ultimate goal of asset-based assessments isn’t to replace performance data—it’s to enhance it. Knowing how a student got to an answer (or why they didn’t) can make all the difference in determining what to do next.

Here’s an example involving a division problem:

A wooden table with four chairs is shown. Text explains each table seats 4, the art class has 33 students, and asks how many tables are needed—an example of using technology in the math classroom to boost student engagement.

When real students were given this problem, they responded with answers like:

33/4 = 8.25, round up to 9 so all kids can sit!
33/4 = 8 with a remainder of 1. She needs 8 tables.
8 x 4 = 32, but 9 x 4 = 36. I don’t know if we can leave one student sitting lonely on the floor, though.

Traditional grading might stop at “correct” or “incorrect” for these responses. But when students are asked to explain their thinking, teachers can uncover a range of reasoning—from successful multiplication strategies to misunderstandings about remainders.

These glimpses into student thinking aren’t just informative—they’re transformative. They can illuminate the performance of students in a deeper, more actionable way. They can help teachers take smarter next steps, and they can help students feel understood, capable, and more like “math people” every day.
