We started today's class by briefly reviewing the concept of scattered plots, and then proceeded to tackle the pre-lesson quiz. Ben worked very well through the problems, and really appeared to grasp the topic. Unfortunately, some of the questions were very fiddly - one of them, for example, involved eyeballing a graph and to my mind the answer could have gone in either of two ways (and sadly we picked the wrong answer). However, Ben appeared quite confident and ready to attempt the test in class later this week - I'm sure he will breeze through it.
