Parabola Picture
	Poor 0 pts	Good 2 pts	Excellent 4 pts
1 Find a parabola in real life and take two pictures of it – one with you in it and one without you in it.	Poor There are no photographs or the photo does not contain a parabola	Good There is only one photograph	Excellent There are two photographs - one with the student and the parabola and the other with the parabola alone
2 Key feature details of standard form a , b & c are described Where and why the parabola was chosen is evident	Poor No description of key features No answers to where and why	Good Description is missing certain features or no answers to where and why	Excellent All key features are listed answers to where and why are evident
3 Use Desmos (online graphing calculator) to graph your parabola: • Insert your parabola into a Desmos graph. Move the parabola so it is in the first quadrant Graph the axis of symmetry	Poor All elements of Excellent are missing/incorrect.	Good Some elements of Excellent are missing/incorrect.	Excellent The parabola is appropriately placed and sized in Desmos. The settings have been changed to make sure size is appropriate and the axis of symmetry is drawn
4 Identify the following and plot them all on your desmos graph: a. Vertex and description b. x-intercepts (if any) & y- intercepts c. Point on the parabola and reflection d. Axis of symmetry	Poor Most elements from Excellent are missing/incorrect.	Good Some elements from Excellent are missing/incorrect.	Excellent All the information is correctly listed on the paper AND is correctly plotted and labeled on the Desmos graph.
5 Use the points inserted in table to graph the parabola on Desmos	Poor No table is shown	Good Table is incomplete or points are inaccurate	Excellent Table is complete and points are accurate
6 Graph your equation, making sure it accurately depicts your parabola	Poor The equation was not graphed in Desmos	Good The equation does not accurately depict the parabola in the picture	Excellent The parabola from the equation is graphed in Desmos and accurately depicts the parabola in the picture
7 Reflection question is answered about how well the curve matches the real life parabola	Poor No answer to reflection question	Good Answer is incomplete or not clear	Excellent Answer is complete and clear
