Geometric transformations on a coordinate plane

Exploring using a negative scale factor on a coordinate plan

Students were asked to graph a quadratic equation, find the preimages vertex, and four other ordered pairs ( two on the left side of the vertex, and two on the right side of the vertex), they were then asked to translate, reflect, rotate,and reflect again. Then give five ordered pairs of the image based on the preimages ordered pairs.

	Did not Complete (N/A)	Rarely Completes 1 pts	Sometimes Completes 2 pts	Often Completes 3 pts	Always Completes 4 pts
Graphing of Preimage	Did not Complete Student did not graph a parabola	Rarely Completes Students did not graph the parabola correctly, but graphed a parabola, and followed instructions for finding the vertex but three or less of the 4 other ordered pairs incorrectly	Sometimes Completes Students did not graph the parabola correctly, but graphed a parabola, and followed instructions for finding the vertex and found 4 other ordered pairs correctly	Often Completes Students graphed the parabola correctly and followed instructions for finding the vertex but three or less of the 4 other ordered pairs are incorrect.	Always Completes Students graphed the parabola correctly and followed instructions for finding the vertex and 4 other ordered pairs correctly.
Transformation Accuracy	Did not Complete Student did not perform any of the sequential transformations.	Rarely Completes Student performed 1 of the 4 sequential transformations correctly.	Sometimes Completes Student performed 2 of the 4 sequential transformations correctly.	Often Completes Student performed 3 of the 4 sequential transformations correctly.	Always Completes Student performed all 4 of the sequential transformations correctly.
Conclusion	Did not Complete Student did not make a conclusion.	Rarely Completes Student made an incorrect conclusion but and did not use specific geometric terminology.	Sometimes Completes Student made an incorrect conclusion but and used specific geometric terminology.	Often Completes Student made a correct conclusion but did not use specific geometric terminology.	Always Completes Student made a correct conclusion and used specific geometric terminology.
Final product quality	Did not Complete There is not final product to evaluate, student did not attempt problem.	Rarely Completes Final product is overall messy, and it is clear the student did not take care to turn in quality work. Student did not edit for errors.	Sometimes Completes Final product is messy in places, and the student took little care to turn in quality work. Student did not edit for errors.	Often Completes Final product is neat, and the student took care to turn in quality work. However, the student did not carefully edit for errors.	Always Completes Final product is neat, and it is clear that the student took great care to turn in quality work. Student edited carefully for errors.
