# Web Quests

## CHAPTER 6

## MYSTERY ELEVATION

**TASK CONTEXT**

In this Web Quest, students will continue their work with integers
by exploring points of elevation on the Web. Students will choose ten
points of elevations from selected web sites – one of these points
of elevation will be their mystery location. Using the skills they have
learned in Chapter 6 of Nelson Mathematics 7, such as comparing, ordering,
adding and subtracting integers, students will create clues for their
mystery point of elevation. They will exchange their clues and list
of ten elevation points with a partner. The partner will then guess
which point of elevation in the list is the mystery location.

This Web Quest provides a twist on the Chapter 6 Task: Mystery Integer
(Nelson Mathematics 7, p. 222).

### GOALS

**7m1** compare, order, and represent integers

**7m10** compare and order integers (e.g., on a number
line)

**7m21** represent the addition and subtraction of integers
using concrete materials, drawings, and symbols

**7m22** add integers, with and without the use of manipulatives

### MATERIALS

paper and pencil

calculator (optional)

counters (optional)

number line (optional)

### INSTRUCTIONAL PROCESS

**FROM STUDENT PAGE**

**INTRODUCTION **

Have you ever stood on
a hill or mountain and wondered how high up you are? Finding out the
elevation of a place would answer this question. Elevation is the height
of land, like a mountain or a valley, in relation to sea level. Do you
think it is possible for land to be below sea level? Do you wonder where
the highest elevation in the world is? What about the lowest?

**NOTES FOR TEACHER**

As a group, read the
Introduction. Discuss with students possible answers to the questions
presented.

**TASK
**

As a world explorer, you decide to travel to
a location that you have found information about on the Internet. You
want people to guess the elevation of the location you are in. To create
a puzzle, you choose ten different points of elevation in the world
using the Internet. One of these points will be your mystery location.
You then create five clues for your point of elevation. Provide people
who want to solve your puzzle with your list of ten elevation points
and your clues. Follow the steps in Parts A, B, & C to complete
your quest.

Note: Part A and B
of the Task can be done individually or in pairs.

Together,
read the Task section of the Web Quest. Ensure that students are clear
on what is expected of them.

Part A

1. Choose ten points
of elevation from the web sites listed below. The points of elevation
you choose must include:

Part C

1. Exchange your list and clues with a partner.
Have him or her try to find your mystery location.

2. Once both you and your partner think you have
found each other's mystery location, join up and find out if you are
correct. Discuss with your partner if there are any possible ways to
improve your clues.

3. Make any necessary changes to your
clues.
