Hi Janet,
I'm currently a computer tech teacher, but I have
experience with teaching math from 6-12 grade.

The math lessons below look great. What is "the
Mathematics Teacher?" Do you tie/string these lessons
together? Or are they separately distributed? I like
the flaming Function and M&M problems the best!

A computer tech lesson I have put together that
integrates math and geography is below It should take
the students about 2-3 weeks to complete. Tell me what
you think? How many days do you think your kids would
take to do this project - say in a 45 minute day.

'Round the World in 80 Days

Mathematics and Geography integration to teach
students about the world is to have them plan an
80-day plane trip around it.

Planning a round the world trip by air seemed simple
at first but they soon find they have to know
something about world cities and how to keep records.

Teams of 2 plan a trip around the world, by air,
beginning from our home base. They had to touch down
in at least six major cities, roughly plotted around
the planet. They used a classroom globe/map to choose
the, major cities they would visit before we sat at
the computers.

The students are provided web sites to identify and
learn about cities around the world; Internet Travel
Network (http://www.itn.net), to learn about air
travel; and Mapquest.com, to learn about in car travel
and driving directions. Students learn to identify the
names of destination cities and the dates and times of

Students record their destination and travel times on
a chart - column one became travel time, while column
two became connections of "down" time. Some students
will have success getting half way across the globe,
then have to change their destination cities when they
found there were no connections available. Eventually
every one makes it back home and tallies their times.

Objectives 1:

Find and identify each at least 1 city from at least 6
countries from an approved book or online source.

Using Microsoft Word, write 1 original paragraph (3-7
sentences) describing what and where your travels will
take you to visit - for a total of at least 6
paragraphs. Name this file in the following format:
first initial, last name-, ane.doc (for example:

Objectives 2:

Figure out which cities/towns you will visit and
method of travel (car, train, plane).

Visit www.itn.net and/or mapquest.com with teacher and
plan itinerary.

Objectives 3:

Map the best route using the least miles and time to
complete your trip back home to Merrimack, New

List your route's itinerary in an Excel spreadsheet
and calculate cost, miles, and time subtotals for each
leg in trip and total trip. Name this file in the
following format: first initial, last name-, ane.xls
(for example: eohare-ane.xls).

Objectives 4:

Link Excel spreadsheet file into Word document (from
Objective 1) with an appropriate introduction to the

Create and link 2 graphics to Word document, created
in Adobe Photoshop. Images can be captured from web or
original art scanned in to computer. Image suggestions
include map of the cities of travel, travel method,
site details (beach, boat, skis, animals). Name this
file in the following format: first initial, last
name-, ane#.doc (for example: eohare-ane1.jpg and
