Andy's SSDD Questions 3

This idea is from Craig Barton and is an excellent one (check them out his at website); essentially it is four questions based on the same information. There are four here which use volume, ratio, Pythagoras, bearings, measures, area and perimeter, speed, percentages and bounds as well as other topics. This really should create discussion and a deeper understanding of the topics covered on top of ensuring that students actually read the question. I hope these are worthy! I will be using these as starters or plenaries.
