"This is a great activity to teach what I think is a tedious topic .. makes it real life and lays it out perfectly for students!"

Description

I use this performance task assessment at the conclusion of our unit on triangle properties. Ultimately the unit is about making strategic use of mathematical tools, an idea that is explored through the following content items:
* Perpendicular bisectors and angle bisectors.
* Triangle medians and midsegments.
* Triangle centers: circumcenter, incenter, orthocenter, centroid.
* Geometric constructions: compass & straightedge, paper folding, geometry software, and coordinate geometry.
This particular assessment evaluates several content items and their skills with the coordinate geometry tool. I have included three versions of the assessment, to accommodate varying levels of student ability: A, B, and C, in ascending order of difficulty. Answer keys and student rubrics are included. Aligned with common core standards for high school geometry.

Also included is a cover sheet with common core standards alignment, student objectives, essential questions, and teacher notes.

The complete file (minus answer keys) is available for free preview on the right. Feel free to take a free look before you purchase.

I am a new seller. Your feedback is my foundation to s good start. Follow me and be updated as I post new items.

Used this resource with my geometry students to help solidify the properties of medians and midsegments in triangles.
