That makes it MUCH easier for the students to work with the properties of quadrilaterals--most students can 'see' the properties and don't need to memorize them.Pam Richmondhttps://www.blogger.com/profile/08289667890941104285noreply@blogger.comtag:blogger.com,1999:blog-8268773079578019071.post-18414051601501650332019-02-10T05:51:56.616-06:002019-02-10T05:51:56.616-06:00I've used this same story for decadess--even i...I've used this same story for decadess--even in a private church school for a couple of years--and I have to say that it does indeed help get and keep the kids' attention!Pam Richmondhttps://www.blogger.com/profile/08289667890941104285noreply@blogger.comtag:blogger.com,1999:blog-8268773079578019071.post-81653303043312662512018-09-24T03:03:39.100-05:002018-09-24T03:03:39.100-05:00I wonder why so many teachers accept to mix inclus...I wonder why so many teachers accept to mix inclusive and exclusive definitions.

I've not thought of teaching shapes using the "family tree" method before; great idea! I will note that I also use the inclusive definition of trapezoid (as outlined in the Euler's Diagram on Wikipedia: https://en.wikipedia.org/wiki/Quadrilateral#/media/File:Euler_diagram_of_quadrilateral_types.svg ) so I think my tree might have some more cousins :)Cimorenehttps://www.blogger.com/profile/05262697819499570461noreply@blogger.comtag:blogger.com,1999:blog-8268773079578019071.post-66541481412781833632017-02-24T15:54:42.996-06:002017-02-24T15:54:42.996-06:00I use the inclusive definition of a Trapezoid: a q...I use the inclusive definition of a Trapezoid: a quadrilateral with at least one pair of parallel sides with my students. It makes more sense that a parallelogram is really just a special trapezoid. Then it will follow that a Rectangle is really a special isosceles trapezoid.

I was wondering the order you teach this in? I have my kids add to their family tree as we got through each quadrilateral. In the past, I spread it over 3 days (we have 90 min blocks), doing the properties first and then going into using algebra in the same day. If you go through this whole story do you teach all the properties in one day?Beckynoreply@blogger.comtag:blogger.com,1999:blog-8268773079578019071.post-88737273922312411222016-05-11T16:07:42.174-05:002016-05-11T16:07:42.174-05:00This is awesome.
