Amazon today announced a new kids show in development from Amazon Studios. Prime Instant Video has greenlit the pilot for interactive math-based puzzle show Sara Solves It.

Here’s Amazon’s official synopsis of the show:

Viewers follow brother and sister duo Sara and Sam on absorbing and relatable mysteries that spring from the questions young children encounter in their daily lives. Each mystery is an interactive, math-based puzzle that the home viewer can solve along with the characters.

Sara Solves It is created by Carol Greenwald, the Emmy award-winner who produced shows like Curious George and Arthur and Angela Santomero, who worked as a writer and producer on Blue’s Clues.

Amazon says that this makes 12 different pilots currently being produced by Amazon Studios. Whenever those shows come to fruition, Amazon says that they will stream them on Prime Instant Video for free.

Amazon is not just working on original series, but has also been busy snatching up content – much of it as exclusives. Last month, they bascially stole the popular PBS series Downton Abbey from Netflix and Hulu, and they also announced that they will be the exclusive online home of FX’s Justified and the upcoming CBS drama Under the Dome.

Oh, ans speaking of original kids shows. Netflix will debut their first original children’s series in December.
