Death Star Maths - Standard Form

Inspired by the imminent release of the new Star Wars film The Force Awakens and an article on the BBC's Newsbeat website (linked in the Powerpoint) I created these standard form questions based upon predictions made by mathematicians regarding the Galactic Empire's Death Star. Just a bit of fun really, but eight standard form questions for your students to try, mainly converting from standard form to "normal" numbers and vice versa, but one calculation at the end. There's also some Death Star facts that could provide extra questions if you wish.
