Digital literacy platform WriteReader is teaming up with Sesame Workshop to feature Sesame Street characters on its multimedia book-authoring platform. It’s the first time the Copenhagen-based edtech company has made third-party content available to its users.

Kids ages three to 10 can use WriteReader to write and publish small digital books to an online library. The platform—optimized for Chrome, Safari and Microsoft Edge browsers—allows kids to take pictures of family, friends or situations in their life and write about them in their own words. Parents or teachers then “translate” the child’s text to conventional writing, and by comparing their book to the edited version, the child can improve his or her writing and reading abilities.

Children using the WriteReader platform will now be able to incorporate characters like Elmo, Cookie Monster and Big Bird into their multimedia books. The partnership with Sesame Workshop will also see Sesame Street characters featured in suggested activities and lesson plans on the platform. Activities focused on friendship and empathy lead the program and were created in consultation with Sesame Workshop’s education team.

Registering for a WriteReader account is free for parents and educators. According to WriteReader, children are more likely to excel when they are engaging with the material as active learners.

In March, Sesame Workshop signed a deal with interactive library platform hoopla digital to bring Sesame Street titles—including eBooks, e-comic books and TV episodes—to participating libraries across the US and Canada. Last year Sesame Workshop also partnered with the kids learning platform Epic! to provide Sesame Street content to its subscribers.
