Lesson Steps:I. Introduction

a. Introduction to the Unit

Kaitlin Troost

Integrative Unit on WWIIo WWII is to this day the largest war in history. It involved

countries from all around the world and caused more casualties than any other war. WII impacted the entire world, including the US. WWII impacted our economy, our beliefs, and who we consider to be friends and enemies. It impacted every person who fought in the war and those whose husbands, fathers, grandfathers, etc… fought in the war.

o There is a multitude of data associated with WWII. In this unit, we will be looking at how to represent this data with various types of graphs and measures of central tendency. By studying data analysis we will be able to see and represent how WWII impacted the US and many other nations around the world.

Explain the final assessment o Throughout this unit, you will be learning about different types

of graphs and how to represent data using these graphs. At the end of the unit, the final assessment will be to use data on WWII to plot two different types of graphs. In the final assessment, students will also be required to use WWII data to calculate the mean, median, and mode of this data

The types of graphs and measures of central tendency will be taught throughout this unit.

o Handout Rubric: this will be discussed in further detail laterb. WWII Graphics Poster

i.) The poster will be hanging up in the classroom. After discussing the final assessment, reference to the poster and how it gives examples of what is expected on the final assessment. Tell the students that we will discuss the poster in detail when we are done learning about the various types of graphs. Thus we will not deal with the poster at this point, but students may look at it in their free time.

c. Pre Assessmenti) Description

Show various engaging examples of data analysis graphs (PowerPoint)

o Students should be in small groupso In these small groups, students will discuss their

observations of the graphs. After students have been given time to discuss their observations, talk about the observations as a class using PowerPoint slides 3 and 5

Survey the class with two questions (last slide of the power point) and graph the data as a class using either bar or line plot

II. Bodya. Line Plots

Purpose: a display of data that shows how many times each data value occurs. Each time a data value occurs, a mark is made above that value on a number line (textbook page 7).

Exampleso Textbook page 6: Exploreo Have students get into groups of three and come up with their

own line plot. The teacher will observe and provide feedback.

Ideas: how many sports teams can you name, how many bathrooms do you have in your house, what is the age range for students in the class, etc…

b. Line Graphs Purpose: a line drawn through pairs of associated numbers on a grid.

It is usually used to show changes over time (textbook page 24). Examples

o Textbook page 24: Example 3o http://www.nationalww2museum.org/assets/pdfs/lesson-

plan15.pdf See page three of the website. As a class analyze the

data of US active military personal from 1939-1945. Using the set up graph below the given data, graph the data using a line graph. (See page 6 of website for answers).

Discuss the meaning of the graph as a class. Ask the following questions. (Answers are in italics).

o What was the trend in the size of military between 1939-1945? Each branch of the military increased during this time.

o What year saw the largest increase of military personal? What event brought about this increase? 1942, because Pearl Harbor happened in December 1941.

o From the data in this graph, which branch of military do you predict had the highest causality rate during WWII? The Army.

III. Closurea. The teacher will summarize the main concepts that we covered today. (See

summarization points below). - Graphs are used all the time outside of the classroom because it takes a bunch of data and represents it visually.- We learned about line plots and line graphs today. What is the difference? A line plot shows how many times a data value occurs while a line graph relates data to show changes over time.

b. If time permits, students will be allowed to work on their assignment, ask any questions, or study the WWII poster in the classroom._________________________________________________________________________________________________

Assignment: Textbook page 9: Practice #1,2,3. Page 25: Alternative Example. Page 27: Practice: #1-9Question: When would you use a line plot/ line graph? How do you determine the range of data? Suggested Answer: You would use a line plot when you are given a display of data and asked how many times each data value occurs. You would use a line graph to show a

comparison of something over time. The range of data is the difference between the highest and lowest values. Thus if the number of deaths in a WWII battle is as low as 8 but as high as 1,000, then the difference is 992, which is the range.

The teacher will take the average of the three columns and that will be the final score for the assignment. The teacher will know that students are achieving the specified learning objectives if the students do the majority of problems correct and if their work shows that they have understood the concepts.
