  2. Grouping Activity An incredible grouping activity for this investigation would be to bring in four different types of canned soft drinks and let each person choose a drink when they enter the classroom. The drink chosen would determine the group they sit in.

  3. Investigation 5 Goals: • To further develop operation sense, the ability to choose the numbers and operations needed to answer specific questions from given information. • To investigate how small quantities can accumulate to produce a large quantity.

  4. Problem of the Day Can you draw two squares in this figure that will put each pig in a separate pen?

  5. Guided Reading Read the following article and write a brief reflection. “Cleaning Up Hog Waste in North Carolina” After individual reflection, share with your group.

  6. Problem 5.1 Going Hog Wild • Assume the growth of the hog populations continues at the rates given in the table for the ten years from 1993 to 2003. • Predict the number of hogs in each county at the end of the year 2003. Which counties will have over a million hogs? • Will the ranking of these five counties be the same in 2003 as it was in 1993? Explain your answer.
