Today we begin reviewing for the unit test on circles and spheres. It covers all of the lessons that we've covered over the last few weeks.
I call this the "Chapter 15 Test," but in some ways this is a misnomer. During this unit, I covered material from eight lessons in five different chapters -- with no more than two lessons from a chapter:
Lesson 8-7: Pythagorean Theorem (for square roots)
Lesson 8-8: Circumference of a Circle
Lesson 10-8: Volume of a Sphere
Lesson 10-9: Surface Area of a Sphere
Lesson 11-3: Equation of a Circle
Lesson 13-5: Tangents to Circles and Spheres
Lesson 15-3: Inscribed Angle Theorem
Lesson 15-8: Isoperimetric Inequality
Here is the distribution of questions from each of the five chapters.
Chapter 8: 7 questions
Chapter 10: 5 questions
Chapter 11: 3 questions
Chapter 13: 1 question
Chapter 15: 3 questions
This test was a bit difficult to assemble. The measurement Chapters 8 and 10 ended up dominating the test since I kept returning through them during the unit. But I know that there are questions from Lessons 13-5 and 15-3 on the PARCC and other Common Core tests, so I made sure to include questions from these -- especially questions were students must calculate angle measures as these are prone to appear on the Common Core tests.
I will spend more of tomorrow's post discussing more of the rationale for including these questions.
