Beyond playing games, it seem that connections could be made to the common
negative numbers students deal with at a young age. If it is 10 degrees below
zero in the morning and 40 degrees in the afternoon, what is the change in
temperature? Then there is Death Valley and the Netherlands which are below
sea level, and the deep trench in the middle of the Pacific ocean. My husband
uses a transit and finds grades both above and below his benchmark. How tall
are the Hawian Islands measured from the sea floor?
It is Friday afternoon and I am truly tired of watching my students gain
an understanding of negative numbers only to have the demon of misinformation
that has been pounded into their heads for the past 9 years pop up.
