Upon reading, I think you really weren't very helpful... bravo. So, apart from WCYDWT, you asked "how would I build this fence" and the kids did the rest of the work.<br><br>I guess the goal now is to make it into a lesson. You've got the workings of fulfilling standards on slope, two-point form of a line, or even linear regression. So, the question would be, what would best extend to one of those areas, without being forced, contrived, or even just uninteresting?<br><br>Oddly enough, the fence looks like it could be parallel to the roof in the background... how tall is that house?mathercizenoreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-2872778983614680622009-05-05T08:51:46.000-07:002009-05-05T08:51:46.000-07:00I didn't notice the roofline, but it wouldn...I didn't notice the roofline, but it wouldn't be difficult to find out how tall it is. I drive by it every day. What would you do with that though?David Coxhttp://coxmath.pbwiki.comnoreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-38237057683597289752009-05-06T13:45:02.000-07:002009-05-06T13:45:02.000-07:00What if instead of telling them everything, you as...What if instead of telling them everything, you asked them to find all possible measurements with the catch that you will only give them a single measurement. For example, if you provide the length of an object in the picture, they should be able to use proportions, calculate angles, and find the length of pretty much everything else. In a geometry class, they should be able to use trig ratios to find the length of the succeeding boards using proportional measurements. It might be more engaging if they calculated a bunch of measurements, and you ended class with a slide of all the measurements you took at the site, and a comparison of the calculated values and the real values. Just a thought.Nickhttp://www.ateacher.org/blog/noreply@blogger.com
