Bell Work  Problems 15, review of finding area. Bell Work will be collected on Friday. Please follow directions, show all work and correct work when needed.
To find the area of a trapezoid, Terrinicka demonstrated how to split up the figure into two triangles. She found the area of each triangle then found the sum of the areas to get the area of the trapezoid. You can also see the solutions for problems 13 above. Remember that the base and height form a right angle.

To find the area of the composite figure, Elizabeth demonstrated how she divided the figure into 3 rectangles. Using the lengths given in the problem, she found values of the missing lengths for rectangle B. There are certainly other ways to find the area of this composite figure, but this is a great example!

After bell work, all classes took a pretest for Unit 6: Statistics. The same assessment will be used at the end of this unit to assess growth and understanding.
Unit 5 tests were returned today and students who were absent Friday took the test. We will review the questions for Surface Area and Volume tomorrow. Students who took the test today will receive their graded test tomorrow. Please have a parent sign both tests for a participation grade. Notice that on the area test, the original test score is circled and the bonus points earned through corrections is posted beside it. Please add those two numbers together for your final test score. This score should be consistent with the one entered online.
Finally, we began examining measures of central tendency and variance through mean, median, mode and range. We will continue this lesson tomorrow or Wednesday after reviewing the study guide for the final exam.

Tuesday, March 11, 2014  Review for Final Exam
Bell Work  Problems 610, review of finding area. Bell Work will be collected on Friday. Please follow directions, show all work and correct work when needed.
#6 TriangleBrooklyn demonstrates how to find the area of the triangle for problem 6. Don't get distracted by the side lengths of 10. Remember that the base and height make a right angle.
#9 Composite FigureAryn, Hannah demonstrates how to find the area by decomposing the figure into a triangle and rectangle. To find the base of the triangle, use the base of the rectangle. To find the height of the triangle, find the difference of the height of the entire figure and the height of the rectangle. Subtract 10 from 16 and you get 6.

#7 TrapezoidOvie and Essence demonstrate how to find the area of the trapezoid by dividing the figure into two triangles. This leads into the formula A = 1/2 (base 1 + base 2) h that Jack will demonstrate below.
Charlize, Hunter and Max demonstrate how to find the area by dividing the shape into a rectangle and two triangles.
Jack demonstrates how to find the area using the formula. Remember that the bases will be parallel to each other and that the formula is derived from the distributive property and the sum of the two triangles. Both triangles share the same height and both areas must be divided by 2, so those are your two common factors.

#8 Composite FigureCamron demonstrates how to find the area of the composite figure by dividing the figure into two rectangles!
#10 Surface Area and Volume of a Rectangular PrismEmily uses the given dimensions to create a 3d drawing. Then, she creates a net to organize the area of each face in order to find the surface area (SA). For volume, remember to multiply the area of the base by the height. 80 cubes fit on the base and since the height is 2, there are 2 layers of 80 cubes for a total of 160 cubic centimeters.

After Bell Work, all classes set up an answer sheet for their study guide and received a study guide. Showing organized work for all problems where work is needed and getting this signed by a parent by Thursday will earn students 10 bonus points on their final exam! Students should complete their study guide for homework as we will review these questions in class tomorrow.

3rd Quarter Final Exam is tomorrow, Thursday, March 13th.
Thursday, March 13, 2014  Third Quarter Final Exam
No bell work due to Final Exam.
Friday, March 14, 2014  Mean, Median, Mode, Range and Outlier
Bell work  Finish completing the "Mean, Median, Mode, and Range Graphic Organizer" using the following PowerPoint and/or notes on the back of the organizer. Then, complete problems 1620. Given a set of data, find the mean, median, mode, range and outlier. Please follow directions, show all work and correct work when needed. Turn in problems 120 for a final 20% grade for Quarter 3.

Classwork  Following bell work, we watched a Brainpop video over mean, median, mode and range. The following slides sum up the video.
Data SetThe data set included 12 sample test scores.
MedianTo find the median, order the numbers from least to greatest. Find the value in the middle where half of the numbers to the left are smaller and half of the numbers to the right are larger. If there are two middle numbers, the median is the arithmetic mean of the two middle numbers.
RangeTo find the range, subtract the smallest value from the largest value in a set of data.

MeanTo find the mean, find the sum of the values in the data set, then, divide the sum by the number of values in the data set.
ModeTo find the mode, list the value(s) that occur most often. If there is more than one value occurring the same number of times more than the other values, then both are modes. There is no mode when all the values occur an equal # of times.

After the video, students took a quiz over mean, median, mode and range in order to collect data for our dot plot. We will finish plotting our data on Monday using the following paper.
