African Storybook vs CK-12 FlexBook 2.0

African Storybook develops and publishes picture storybooks in African languages to support children’s literacy, enjoyment and imagination. Its stories and tools are intended for children aged two to ten, including early childhood and the first three years of primary school. The free Reader app lets parents and children access books offline. With the free Maker app, people can create storybooks offline on a phone or tablet, then publish them to the website once connected. Website tools also support creating, translating and adapting picture books, and readers can download titles for offline reading or print them. Stories may be read, copied, adapted and translated without payment or permission, subject to attribution and any non-commercial restriction attached to a particular story. Creating, adapting or translating requires registration; users must be at least 18 or have parent or guardian permission. The site distinguishes ASb-approved stories from those made on the website or in the Maker app that have not been checked. It also offers video and written guidance on using and developing picture storybooks. The initiative is free, with Android, iOS and web access.

CK-12 FlexBook 2.0 provides customizable digital textbooks for K–12 subjects including science, math, and social studies. Lessons can combine text with PLIX interactives, simulations, adaptive practice, and related learning materials. Adaptive Practice draws questions from a library of more than 150,000 and adjusts selections based on student answers. Teachers can assign lessons, videos, interactives, and practice to whole classes or differentiated groups, then view progress reports. Educators can reorder chapters and edit or add content in customized FlexBooks. The service works in browsers on laptops, desktops, Chromebooks, tablets, and mobile devices, and is listed at free. Standalone Simulations and PLIX Interactives require a tablet-size screen or larger. Users may download PDFs of FlexBooks they create or customize, though interactive content may not render; CK-12-created PDFs are not downloadable. CK-12 says it is still converting all core content to FlexBook 2.0. Listed SSO or LMS partners include Google Classroom, Canvas, Schoology, Kiddom, Clever, and ClassLink.
