A Day 9/17/10

Periods 1 and 4 Geometry

Objective: Students will calculate linear equations in order to prepare for our unit in segment length measurement and angle measurement.
Following the warm up, students checked their homework on linear equations, and Mrs. Dennard put several on the overhead to explain them; students put several problems on the white board, in 1st period, too. Students started in segment lengthe measurement, completing # 1-15 in section 1-4.
All Geometry students are now able to access to textbook online. If you have forgotten you password or user name, see Mrs. Lynch.
1st period homework: Complete the linear equations on p.24.
4th period homework: Text pp 30-31,#33-36 and 42-46, and on p.33 #87-97.

Next class: segment and angle measurement.The will be a brief exit quiz at the end of the next class.


Period 3 Math Studies IB
Objective: Students will calculate the variance statistic in order to analyze the spread of a set of data. Following the warm up, Mrs.Dennard spoke to each student scoring less than 70% on the quiz this week. All were instructed to complete an error analyses to be completed by Tuesday, several were encouraged to take a retest.
Mrs. dennard also spoke to the class about study skills, and told them about the study skills workshops planned for October for Honors level students.
The lesson on variance was was explained as simply another measure of data dispersion, and it is calculated by squaring the standard deviation statistic.
Classwork: H&H pp 152-153,#4-7.
Homework: Complete classwork.
Next Week: Scatter plot correlation (Oxford) and Probabiility (Chapter 14 in H&H.
