Site Feedback

Give your students feedback,
meaningfully and efficiently.

Students Show Step-by-Step Work

Students can start with a blank Free Math document, copying down and working through problems just as they would in paper notebooks.

Students save their work as a file and submit it through an LMS in response to an assignment.

Embrace Visual Learning

Students can add digital drawings and graphs to their assignments.

Including freehand or straight lines, basic shapes, and text.

Bridge the Gap Between Paper and Your Favorite Digital Tools

Students can include images in their solutions.

Including snapping a picture of written work with their webcam, or quickly pasting an image from another site like Desmos or Geogebra.

Simultaneously Review All Assignments

Complete solutions are shown, grouped by similar final answer.

You can award partial credit and give feedback to students that need help.

You don't need to type in an answer key, Free Math just provides an organized view of all student work.

Free Math App is an excellent tool for seamlessly grading student work without timely preparation. Students are able access any mathematical symbol many word processing tools lack, enabling them to display their math work accurately and quickly.

I would just like to compliment you guys on the work you've been doing with the website. This has been a life saver. All of my classes are using this and some students have had to quarantine but they can still work on the HW and submit it.

Your site has made these difficult times of distance learning so much easier to manage as a teacher. I've raved about your site to several teachers and we're using it in all of our middle and high school classes.

Analytics Show Where Students Struggled

Give feedback on the most impactful problems first,
everything else gets completion points.

No Accounts Or Downloads Required

The entire experience runs right in your web browser.

Direct integration is provided for Google Drive and Classroom, including gradebook integration.

For other LMSes and cloud storage providers, assignments and grading sessions save directly from the browser to files in your downloads folder and from there they can be uploaded to any service you use for your class.

The files can be collected in any LMS, downloaded all together and loaded for grading. After grading, your LMS also easily provides an individual feedback file to each student.
