OK the first ones that came to mind were Jaws, then Rollerball. I was 11.
I'm sure my parents took me to see Disney films when I was younger, but the scary/violent ones popped into my memory first, go figure.
LoF Fractions is the first book where I can see the problems getting more challenging and thought provoking. The algebra books look interesting, but we are not quite there yet.
I've been looking at MM, but the pages look so busy/crowded. There just seems like there is not enough white space. I recently purchased one of the Fraction books from MM. I'll let DS try it out and see if he feels the same way about the layout.
