My Notes
Ms. Flowers, a math teacher at Rachel Carson Middle School, plans
a fi eld trip for her students every year. On the fi rst day of school,
each student recommends a place where the class should go on the
annual trip.
1. If your teacher were to plan a fi eld trip for your class this year,
where would you like to go? Write your choice below and
explain why this would be a good choice for your class trip.
When the students report to math class, many have ideas about
where they would like to go. Marcus wants the class to go to Death
Valley this year. Th e other students think that Death Valley would
not be a pleasant place to visit so they tell Marcus to convince
them this is a good choice. In his research, Marcus fi nds that Death
Valley is very interesting and could be called “a land of extremes. ”
He was surprised to learn that Death Valley has some high
mountains and some very low canyons. He noticed that some
elevations in Death Valley are above sea level and are listed as
positive numbers, while some are below sea level and are listed as
negative numbers. He also noticed that the online atlas listed sea
level as 0 feet. For a moment he was confused about what these
numbers meant, but then remembered that last year he learned that
these numbers are called integers.
2. In the chart below, list what you already know about integers
and what more you would like to learn about them. When you
are fi nished, your class will make a chart showing everyone’s
information.
