investigates turnover rates in a company over some years.
RESPONSES TO TURNOVER RATE ACTIVITY [HTML]
A guy walks into a 7-11 store and selects four items to buy. The clerk
at the counter informs the gentleman that the total cost of the four
items is $7.11. He was completely surprised that the cost was the
same as the name of the store. The clerk informed the man that he
simply multiplied the cost of each item and arrived at the total.
The customer calmly informed the clerk that the items should be added
and not multiplied. The clerk then added the items together and informed
the customer that the total was still exactly $7.11. What are the
exact costs of each item?
My Ford Bronco was fitted at the factory with 30 inch diameter tires.
That means its speedometer is calibrated for 30 inch diameter tires.
I "enhanced" the vehicle with All Terrain tires that have a 31 inch
diameter. How will this change the speedometer readings? Specifically,
assuming the speedometer was accurate in the first place, what should
I make the speedometer read as I drive with my 31 inch tires so that
the actual speed is 55 mph?
of groove on an Long Play record [HTML]

groove on one side of a long-play (33 1/3 rpm) phonograph record?
Ladder and Box A ladder
meters long leans against a wall, reaching over the top of a box that

DESIGNED UNITS & ACTIVITIES
Math in Motion [HTML]
The purpose of the lesson is to emphasize
the fundamental characteristics of functions, as well as let the students
"experience" functions. The students will do this by graphing
their movements with a CBL, and trying to evaluate which movements will
create a particular type of function.
The purpose of the lesson is to utilize
some applications of linear and quadratic equations and show how these
would apply in the real world, using hands-on investigations.
A Risky Encounter [HTML]
If a contagious disease is in existence,
this disease can be transmitted through risky encounters and be spread
throughout the entire population. This activity, using your class
as a population that encounters one another during five stages, documents
the risky encounters with other people.
The Verhulst Model of the Population [HTML]
If a contagious
disease is in existence, this disease can be transmitted through risky
encounters and be spread throughout the entire population. This activity,
using your class as a population that encounters one another during
five stages, documents the risky encounters with other people.
Mama Sid's Pizza [HTML]
Every Friday night my friends and I go
to Mama Sid's for dinner. If we want to order a different pizza every
Friday for a whole year, how many toppings would Mama Sid's have to
plan investigating combinatorics in a restaurant environment.

A car rental agency charges $37.50 per day and $0.23 per mile or fraction
thereof to rent a car. A bus ticket cost $85.75 round trip. Under
what circumstances is each option more economical?

Estimating Area: In medicine, calculation
of body surface area is sometimes very important. For example, severe
burns are usually described as covering a percentage of the body surface
area. Some chemotherapy drug dosages are based on body surface area.
How might body surface area be measured? What factors influence the
accuracy of the estimates?
Buying a Used Car: How does the age of
a used car affect its price? How does its age affect its repair costs?
What is the best age at which to buy a used car?
Buying on Credit: A credit card company,
whose motto is "see the world on credit," charges 1.387% interest
on the unpaid balance in an account each month, and requires a minimum
payment of 2% of the outstanding balance each month. Suppose you charge
$100 each month and make only the minimum payment each month. How
much will you owe at the time of your 24th bill? Assuming you pay
the whole bill at the end of that period, how much will be interest?
Lottery Winnings: A lottery winner died
after five of the twenty years in which he was to receive annual payments
on a $5 million winning. At the time of his death, he had just received
the fifth payment of $250,000. Because the man did not have a will,
the judge ordered the remaining lottery proceeds to be auctioned and
set the minimum bid at $1.3 million. Why was the minimum bid set so
low? How much would you be willing to bid for the lottery proceeds?
Hospital Quality: As health care director
for your company, your job is to select which of two local hospitals
you will send your employees to in case of emergency.
Rounding Off: In a certain multi-million
dollar company, Division Managers are required to submit monthly detail
and summary expense reports on which the amounts are rounded, for
ease of reading, to the closest $1,000. One month, a Division Manager's
detail report shows $1,000 for printing and $1,000 for copying. In
the summary report, the total for "printing and copying" is listed
as $3,000. When questioned about it by the Vice President, he claims
that the discrepancy is merely round-off error. In subsequent months,
the Vice President notices that such round-off errors seem to happen
often on this Division Manager's reports. Before the Vice President
asks that the Division Manager re-create the reports without rounding,
she wants to know how often this should happen.
Rules of Thumb: Some drivers learn the
rule of thumb, "Follow two car lengths behind for every 10 miles per
hour." Others learn, "Stay two seconds behind the car ahead." Do these
two rules give the same results? Is one safer than the other? Is one
better for roads with speed limits of 45 or 50 miles per hour and
another for highways on which the speed limit is 65 or 70 miles per
