Production Details:
After basic KIT construction, the unit undergoes six weeks of
onsite ROM programming and burn-in testing. Listed features are
installed during this period. Since MOMCAT uses local suppliers,
there may be a variation between individual units. Some of the
units may not meet general standards. MOMCAT's quality assurance
may reject inferior units. Users may sometimes salvage rejected
units. Beware of Far East clones. These may violate more...

## A History of Math Education

Saw this one on a professor's door:
The evolution of mathematics education
during the last 30 years.
1960's
A peasant sells a bag of potatoes for \$10. His costs amount to 4/5 of his
selling price. What is his profit?
1970's
A farmer sells a bag of potatoes for \$10. His costs amount to 4/5 of his
selling price, i.e. \$8. What is his profit?
1970's (New Math)
A farmer exchanges a set P of potatoes with a set M of money. The cardinality
of the set M is equal to \$10 and each element of M is worth \$1. Draw 10 big
dots representing the elements of M.
The set C of production costs is comprised of 2 big dots less than the set M.
Represent C as a subset of M and give the answer to the question: What is the
cardinality of the set of profits? (Draw everything in red).
1980's
A farmer sells a bag of potatoes for \$10. His production costs are \$8 and his
profit is \$2. Underline the word "potatoes" and discuss with your more...

## The Evolution of a Math Problem

Math 101Last week I purchased a burger at Burger King for \$1.58. The counter girl took my \$2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register. I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried.Why do I tell you this? Because of the evolution in teaching math since the 1950s:
Teaching Math In 1950A logger sells a truckload of lumber for \$100. His cost of production is 4/5 of the price. What is his profit?
Teaching Math In 1960A logger sells a truckload of lumber for \$100. His cost of production is 4/5 of the price, or \$80. What is his profit?
Teaching Math In 1970A logger sells a truckload of lumber for \$100. His cost of production is \$80. Did he make a profit?

## The History of Math

Teaching Math in 1950:
A logger sells a truckload of lumber for \$100.
His cost of production is 4/5 of the price.
What is his profit?
Teaching Math in 1960:
A logger sells a truckload of lumber for \$100.
His cost of production is 4/5 of the price, or \$80.
What is his profit?
Teaching Math in 1970:
A logger exchanges a set "L" of lumber for a set "M" of money. The cardinality of set M is 100. Each element of M is worth one dollar. Make 100 dots representing the elements of the set M. The set C, the cost of production, contains 20 fewer points than set M. Represent the set C as a subset of set M and answer the following question: What is the cardinality of the set "P" of profits?
Teaching Math in 1980:
A logger sells a truckload of lumber for \$100.
His cost of production is \$80 and his profit is \$20.
Your assignment: Underline the number 20.
