Today in Math 10 I talked about bearings - angles measured compared to true north. Students practiced a little, and then they used their new skills to solve a geocaching puzzle which I have been working on for 2 months. The SMART board displayed the needed map, and the screen capture feature allowed them to take turns finding a bearing of 245 degrees and then measuring distance along the bearing arrow. Success! Their calculations lead them straight to where I thought the waypoint was, but they did a better job on the drawing than I could do on a small screen or piece of paper. After calculating radii of intersecting circles, numbers of squares in a complex figure, bearings, and figuring out how to construct a huge compass they are ready to actually go out an test their work.
Next Thursday we have a field trip to find waymarks 1 and 2 as well as the geocache.
I just have to find it first so we can have a successful trip in a limited time frame.
I love it when technology helps!
Life really is good.
