JR:  Write the standard form of an equation of an ellipse and explain the components. How is equation similar/different to the equation of a circle?
Pg. 516 #1, 3 and Pg. 517 #6.

Today's Goal: Students will become familiarized with an ellipse as a conic section, including the creation of an ellipse and the formula for creating this shape.
5/26 For each, categorize as a circle, ellipse or parabola and define the center(s), foci, vertices, and directrix if they apply.
• • • Mini-Presentation Jigsaw Activity.
• Each person is assigned to a group and must contribute equally. If you are absent on Tuesday, begin working independently on the Task for group 4.
• Each group is assigned an application problem.
• Today you will have work time on the application problem as a group.
• Friday, your group will present your solution to the class.
• Your group will turn in a single, nicely written copy of your solution for a 10 point quiz grade. Ensure all group members names are on the written solution. This will be graded using the standard testing rubric, provided students are contributing fairly, all students will receive identical grades.
• If you use resources outside of your group, you must cite additional assistance using APA format. Please ask Dr. Edge or Mr. G. if you have additional questions.
• Presentations will be informal, but will count for 5 class participation points, if you have an unexcused absence on May 29, you will earn a zero. Excused absences will need to make arrangements no later than your first day returning to class.
• See Homework Section for activity details.

JR: What are your responsibilities in your group? Specifically, describe what you are going to do to contribute to this project outside of class?

Project Information
Tasks listed by Group Number:
Provided students are contributing fairly, each group member will receive identical grades. If a group member is:
• Making extraordinary contributions
• Not contributing.
• Taking-over group responsibilities.

Please inform Mr. G as soon as possible, this may positively or adversely affect a single group members grade.

5/27 & 5/28
Smarter Balance Assessments (ELA and Math)
If you are in class, use the time to either prepare for your Friday presentation or begin studying for the Final Exam.
