Curriculum: Katherine Baker Teacher / Team Name: Topic: Unit 10: Subject(s): Math Learning-Focused Toolbox Date: July 19, 2011 ET Geometry Regular Measuring Length and Area (REG) Days: 12 Grade(s): 9th, 10th, 11th, 12th Key Learning: Formulas for area of figures will be derived and applied to solve problems. Unit Essential Question(s): How are the formulas for area of figures derived and applied to solve problems? Concept: Area of Polygons Lesson Essential Question(s): What are the similarities and differences between the formulas for areas of polygons? (A) How do you use the area formulas to find the areas of polygons? (A) Vocabulary: base, height, center of a regular polygon, radius of a regular polygon, apothem, central angles, composite figures Concept: Concept: Circumference and Area of Circles and Sectors Area of Similar Figures Lesson Essential Question(s): How are the circumferences and areas of circles determined? (A) Lesson Essential Question(s): How is the ratio of the areas of two similar polygons related to the ratio of corresponding sides? (A) How is determining the area of a sector an extension of the area formula? (A) Vocabulary: sectors of a circle, segment of a circle Vocabulary: Additional Information: Sections: 11.1, 11.2, 11.3, 11.4, 11. 5, 11.6 Attached Document(s): Page 1 of 1 Curriculum: Katherine Baker Teacher / Team Name: Vocab Report for Topic: Subject(s): Math Learning-Focused Toolbox Date: July 19, 2011 ET Geometry Regular Unit 10: Measuring Length and Area (REG) Days: 12 Grade(s): 9th, 10th, 11th, 12th Concept: Area of Polygons base height center of a regular polygon radius of a regular polygon apothem central angles composite figures Concept: Circumference and Area of Circles and Sectors sectors of a circle segment of a circle - Page 1 of 1
