A Day, 12/10/10

Period 1A Geometry, grades 10-12
Objective: students will classify triangles, and find the measures of their angles; and use exterior angles of triangles in order to find the reclining angle of a lounge chair. Following the warm up, Mrs.Dennard taught the lesson on the Triangle Angle-Sum Theorem, and reviewed 5 problems to check for understanding, then the classwork was assigned: Text pp 134-139,#1-30,evens only. Any work not completed in class is to be completed for homework. Students took a brief quiz (open book) on Chapter 3,sections 3-1 through 3-3. The 2nd Quarter project was distributed. This is the Chapter 3 Portfolio Project. It is due Dec 20 - definitely BEFORE the winter break.

Period 4A Honors Geometry Grade 9
Objective: Students will classify polygons and find the sums of the measures of the interior and exterior angles of polygons in order to find the measure of a triangle used in packaging. Following the warm up, Mrs. Dennard answered any questions on the homework assignment (Worksheet 3-3), and then asked student to use their textbooks to complete the Checkpoint Quiz on p. 139. This was a quiz timed for 20 minutes. When all students had turned in the open book quiz, Mrs. Dennard taught the lesson on the Polygon Angle-Sum Theorems, students were guided through the 5 problems in a check for understanding, and then assigned practice problems.
Assignment: Text pp.147, #1-10,13,15.
Homework: Text p. 145 Investigation: The Sum of the Polygon Angle Measures
The 2nd Quarter Project rubric was distributed today. The chapter 3 Portfolio Project is due on Dec.20, definitely BEFORE we depart for the winter holidays.

Period 3 Math Studies IB grade 11
Objective: Students will practice problems regarding descriptive statistics in order to prepare for the Chi-square lessons next week. Following the warm up, students received instruction for today's classwork assignment: Text H&H Chapter 5 Review Sets A,B,and C, multiples of 3. Students well allowed to complete yesterdays' assignment of Chap.5,Ex5I.1,#1-7.
Homework: All practice assignments are done in class at this time so that Mrs.Dennard can be available for questions and observe students doing their own work.
Homework will in the form of a unit project, and will be graded as a test grade. This weekend, the assignment is to prepare 3 questions which might be used in the unit portfolio.
The 3 questions follow the 3 layers of tasks: The A Layer is the highest ordered thinking skill - it is synthesis and evaluation. A problem could be similar to the IB'long' exam question, which ask several question, and use several math processes. The B Layer is the middle layer; it include the analysis and the more thorough comprehension tasks. Some examples of tasks in this area: Error analysis of quizzes; explanations and examples of all unit objectives, and may include section level textbook assignment, or a reflection of an assignment previously assigned. Level C is the most basic level, and includes tasks to promote basic knowledge and comprehension of the objective. These types of tasks may include a poster illustrating all vocabulary words, a test assignment, a poster comparing two related concepts, such as histograms and frequency charts.

Students are encouraged to include content from other classes, and to consider those areas they have had some difficulty understanding in the Statistics unit. For example a scatter plot illustrating migration patterns to or within the United States, statistics of Vietnam war inductees, say, enlistees vs draftees, and their rates of survival. There are numerous applications to consider in Biology and English, You could even pose a statistics question in Spanish, or French and require that the answer be in the same language. Please be creative!
