Amazon has purchased TenMarks, an online math tutoring service, the companies announced Thursday.
Dave Limp, Amazon's vice president of Kindle, said in a press release that TenMarks is a good match for Amazon. With this acquisition, Amazon will focus on developing education content and applications.
"Amazon and TenMarks share the same passion for student learning. TenMarks's award-winning math programs have been used by tens of thousands of schools and Amazon engages with millions of students around the world through our Kindle ecosystem," he said in the release.
TenMarks offers personalized online math instruction and practice, including video lessons, for K-12 students.
Education is an area other tech giants, like Apple, are trying to break into., a free online tool that lets schools and businesses manage a fleet of Kindle tablets and wirelessly distribute Kindle books, documents, and apps.
