 * 2-D-2_Halter – Blog Lesson Plan **
 * 1) How to use a blog which has been set up by a teacher for a class
 * 2) Measures of central tendency (mean, median, mode)
 * 3) Five-number summary as used for box-and-whisker plots
 * I want students to begin to become proficient reading and commenting on a blog in order to collaborate with one another.
 * I want to students to retrieve data via the internet using a search engine.
 * I want students to learn how to take a set of data and find the three measures of central tendency as well a produce a box-and-whisker plot of their data, which we will later compare to those of other classmates’.
 * Locate the class blog and retrieve information from it (choose a city from a list)
 * Post comments on the blog to communicate with the class (let teacher and classmates know their choice of city and statistical results)
 * Use a search engine to find data on one city’s average daily temperature for the month of July
 * Find the mean, median, and mode of the set of data
 * Find the 5-number summary and make a box-and-whisker plot of the data by hand and with the TI-84 graphing calculator
 * Report back to the class via additional comments on the blog
 * Answer questions about their results and their implications
 * Blog about their choice of city to visit or live in during July and why they made their choice
 * Post responses to their classmates’ choices of city in which to spend July
 * Laptop cart or computer lab availability on //Days 2 and 3//
 * Papers with standardized number lines for student box-and-whisker plots
 * Extra graphing calculators for students who didn’t bring theirs to class
 * Introduce the students to our class blog using a demo computer and projector.
 * Have students choose a city from a given list found on the blog
 * Demonstrate use of various search engines on topics they choose and I suggest.
 * Review definitions of measures of central tendency and how to find each one by hand and using the graphing calculator.
 * Teach the 5-number summary (minimum/quartiles 1,2,3/maximum) and how to make a box-and-whisker plot by hand and using the graphing calculator.
 * Practice the statistical skills on data sets given to the students.
 * In a computer lab, or using a lap-top cart, give students time to find the class blog and teacher’s entry about the cities for which they will find temperatures, and add a comment on the blog indicating which city’s data they are using.
 * While they are at the computers, students should use a search engine to find their data (the most recent year’s average daily temperatures for the month of July) and print their data.
 * Students can then begin to find the mean, median, and mode for their city’s data set, and to find the 5-number summary and make their box-and-whisker plot. (Classmates who are more comfortable on the graphing calculator should be encouraged to help their peers.) They should prepare their box-and-whisker plot on given paper (with standardized number lines), with the city named in a title.
 * Collect box-and-whisker plots (make overhead copies for tomorrow)
 * Homework includes going on-line and posting a comment on the class blog which gives the student’s statistical findings for his or her city, including the 3 measures of central tendency and the five-number summary.
 * Display various box-and-whisker plots and ask students to discuss how they can be used to compare cities with respect to their temperatures.
 * Talk about how the means and modes compare to the medians and box-and-whisker plots.
 * Ask students to compose questions they have about the statistics and their implications and post them on the blog. (We’ll need to have computers available again today).
 * Homework is to post a comment in response to 3 peers’ questions, and to make a summary comment which tells which city in which they would like to spend July and why.
