Autograph Video 60 - Co-ordinate Battleships

UPDATE: Supporting worksheet by Brian Arnold! :-) The 60th in Mr Barton's Autograph Video tutorial series. In this video we take a look at an activity I like to use with my classes called Co-ordinate Battleships. I use this either to revise the equations of straight line graphs or even to introduce the topic. Teams take it in turn to launch their missiles (in the form of straight line graphs) in order to sink the ships (the co-ordinates). We look at how you can easily create this page on Autograph, and then some possible extension work after the sea battles are over.
