Examples & Explanations You probably know that the smaller |a| in the standard form equation of a parabola, the wider the parabola. In other words y =.1x² is a wider parabola than y =.2x². How does this relate to the directrix and focus? Adapted from mathwarehouse.com Focus and Directrix of Parabola explained with pictures and diagrams

How does this relate to the directrix and focus? As |a| decreases p increases, ie. the distance between the vertex and directrix and vertex and focus increases.

Assessment July 22, 2013 – State School Superintendent Dr. John Barge and Gov. Nathan Deal announced today that Georgia is withdrawing from the Partnership for Assessment of Readiness for College and Careers (PARCC) test development consortium. Instead, the Georgia Department of Education (GaDOE) will work with educators across the state to create standardized tests aligned to Georgia’s current academic standards in mathematics and English language arts for elementary, middle and high school students. Additionally, Georgia will seek opportunities to collaborate with other states. The press release in its entirety can be found at: http://www.gadoe.org/External-Affairs-and- Policy/communications/Pages/PressReleaseDetails.aspx?PressView=default&pid=123http://www.gadoe.org/External-Affairs-and- Policy/communications/Pages/PressReleaseDetails.aspx?PressView=default&pid=123

35
Assessment As GaDOE begins to build new assessments, please note that our Georgia assessments: will be aligned to the math and English language arts state standards; will be high-quality and rigorous; will be developed for students in grades 3 through 8 and high school; will be reviewed by Georgia teachers; will require less time to administer than the PARCC assessments; will be offered in both computer- and paper-based formats; and will include a variety of item types, such as performance-based and multiple- choice items. The press release in its entirety can be found at: http://www.gadoe.org/External-Affairs-and- Policy/communications/Pages/PressReleaseDetails.aspx?PressView=default&pid=123http://www.gadoe.org/External-Affairs-and- Policy/communications/Pages/PressReleaseDetails.aspx?PressView=default&pid=123

36
Assessment We will continue to work with Georgia educators, as we have in the past, to reconfigure and/or redevelop our state assessments to reflect the instructional focus and expectations inherent in our rigorous state standards in language arts and math. This is not a suspension of the implementation of the CCGPS in language arts and math. ~ Dr. John Barge (excerpt from a letter to state Superintendents from Dr. Barge)
