PreK–12 Content

Building truly immersive and successful curriculum content—for textbooks, digital interactives, and more—has been at the core of Six Red Marbles for decades. Our custom content and assessments have spanned pre–K, elementary school, and secondary school learning, with an experienced content development team producing English language arts, math, science, and social studies curricula. We can align to any educational framework or standards, including state, Common Core, NGSS, and WIDA ELD standards.

Six Red Marbles can create content to work hand in hand with your unique learning framework—or even help you develop your own learning path for students. Our content development team works closely with our learning experience design, creative, and project management teams to ensure that the content we create always puts your goals first.

Adult Learning Content

Our corporate, nonprofit, and education clients come to us because we take a tech-forward approach to professional development materials. We understand the differences among professionals studying to further their careers, students studying to start their careers, and children learning about how the world works—and we leverage learning sciences’ best practices to build adult learning content that professionals actually connect with.

In fact, Six Red Marbles’ learning experience design team works with in-house experts and client services managers to ensure that workforce training products meet and even exceed professional development strategies and workforce education needs.

Higher Education Content

How do you reach the tech-savvy, often overstimulated audiences such as those in higher education? You go to them, using their tools. We use technology and innovation to build interactive courses that engage learners and maximize educational outcomes. Our cross-disciplinary higher education team has a mastery of eLearning design and online learning technologies. We also partner closely with higher education organizations to develop custom curricula.

To date, we’ve built hundreds of online courses and designed custom interactive media for higher education institutions around the globe, from New England to England to Australia. Our higher education portfolio spans assessment, online learning, competency-based education, and curriculum development.

Our content development team taps into decades of real-world experience in all levels of the publishing and education industries.


The Six Red Marbles content team is made up of seasoned educational veterans who understand the nuances of the publishing world. That’s why when it comes to accessibility, we don’t just patch together an “accessible version” of your content. We guide you to develop content through the lens of pedagogical accessibility. We follow current best practices employed by major accessibility auditing and maintenance companies, as well as curate accessible content for students.

Six Red Marbles can develop content that achieves all of the educational standards your organization aims to achieve, all while adhering to the level of compliance you outline—Section 508 or WCAG 2.0 A, AA, or AAA.

The markets we serve know us as thought leaders and innovators.
