Investigation 5Every LITTER Bit

Hurts

Grouping ActivityAn 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.

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.

Can you draw two squares in this figure

that will put each pig in a separate pen?

Problem of the Day

Guided ReadingRead the following article and

write a brief reflection.

“Cleaning Up Hog Waste in North Carolina”

After individual reflection, share with your group.
