Evolution Of Math Instruction In California Public Schools.

   Let's review the evolution of math instruction in the California public schools:

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 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.

Teaching Math in 1990:
By cutting down beautiful forest trees, the logger makes $20.  What do you think of this way of making a living?  Topic for class participation after answering the question:  How did the forest birds and squirrels "feel" as the logger cut down the trees?  There are no wrong answers.

Teaching Math in 2002:
A logger sells a truckload of lumber for $100.  His cost of production is $120.  How does Arthur Andersen determine that his profit margin is $60?

Teaching Math in 2005:
Little Johnny Einstein flunks his California State Achievement Test in math (CSAT) and sues Santa Monica Middle School # 101, School Superintendent Dr. Marilyn Howard, and the entire state legislature for $100 million.  If the NEA lawyer receives 4/5 of the frivolous award, how long will it be before the “Leave No Child Behind” Act bankrupts the entire nation?

Teaching Math in 2015:
El hachero vende un camion carga por $100.  La cuesta de production es...
