Weekly Reader Connections

Teacher Guide: Lesson 3.8

The Weekly Reader Connections feature on Kids' Place Houghton Mifflin Math provides your students with additional information about the topics that appear in the Curriculum Connection feature in their student books.

The article “He's a Winner” sets forth the seven core values held by the United States Army and describes the experience of one boy who won an essay contest on the subject. After students have read the article, ask volunteers to describe some of their own values before assigning the Word Wise activity. Be sure students understand that they display some of their values through their behavior and in the way in which they treat other people. The Data Hunt activity presents information about the Pentagon in the table shown below.

Area of Pentagon building 29 acres
Area of center courtyard 5 acres
Parking capacity 8,770 vehicles
Length of each side 921 feet
Number of floors 5
Total length of corridors 17.5 miles
Rest rooms 284
Drinking fountains 691
Windows 7,754

Located in Virginia, near Washington, D.C., the Pentagon is the largest low-rise office building in the world. Although it is only 5 stories high, it has the largest ground area of any building in the world ? and three times as much floor space as the Empire State Building. You may wish to visit this website for more information, as well as for a virtual tour of the Pentagon. http://www.defenselink.mil/pubs/pentagon/

After having students read the Pentagon Data table, be sure that they know what is meant by the expression “working around the clock” before having them answer these questions.

  1. The Pentagon was built in 16 months by three crews of 5,000 workers each, working around the clock. How many workers was that?
    Answer: 3 x 5,000, or 15,000 workers
  2. What is the perimeter of, or the distance all the way around, the Pentagon?
    Answer: 5 x 921, or 4,605 feet
  3. Approximately 25,000 people work at the Pentagon. Suppose equal numbers of people work in each section. About how many work in each section?
    Answer: 25,000 ÷ 5, or about 5,000 people
  4. Before a section can be modernized, everyone who works there must move somewhere else in the Pentagon. Suppose approximately equal numbers of workers moved from one section into the other four sections. Then how many would be working in each of the other sections?
    Answer: 5,000 ÷ 4 = 1,250 and 5,000 + 1,250; 6,250 workers

Students are then asked to write their own word problem using the data in the Pentagon Data table.
