Demonstrators should be read from bottom to top, but need not be demonstrated sequentially.

 

Elementary Demonstrators

 

•  Sort objects and compare attributes.

•  Explore the properties of relations, including order (i.e., <, >, familial relationships, longer than).

•  Explore logical thinking (i.e., analogies and syllogisms).

•  Compare and contrast the structural characteristics of varying numeration systems (e.g., other bases, Roman numerals, cuneiform).      

 

Middle School Demonstrators

 

•  Use order of operations with rational numbers.

•  Apply field properties to solve problems and equations (e.g., pencil/paper and mentally).

•  Communicate (by modeling, verbal/ written explanation, and graphing on a number line) an understanding of order relations and inequalities.

•  Use and compare various number systems.

 

High School Demonstrators

 

•  Investigate and solve optimization problems.

•  Analyze the structural characteristics of the real number system and various subsystems.

•  Communicate the logic of algebraic procedures.

•  Analyze similarities in various mathematical systems.

•  Use deduction in an axiomatic system.  

 

Sample Teaching/Assessment Strategies

 

Graphic Organizers: Compare/Contrast Structures, Mapping, Matrix / Problem Solving: Heuristics, Inquiry, Debate, Oral History / Technology/Tools: Calculators, Computers, Games, Manipulatives

 

These sample strategies offer ideas and are not meant to limit teacher resourcefulness. More strategies are found in the resource section.

 

Ideas for Incorporating Community Resources

 

•  Invite a variety of ethnic representatives in the community to bring the class samples of their number systems.

•  Examine, with a local architect, buildings in the community that illustrate the "Golden Rectangle."

•  Interview police, attorneys, and physicians on the effect of using DNA for identification in criminal cases.

 

Core Concept - Mathematical Structure

 

Sample Elementary Activities

•  Solve and create analogies:

     a. inch: yard: centimeter: METER;

     b. ball: circle: BOX: rectangle P

•  Examine the Fibonacci numbers and find examples in nature (petals on a flower, birthrate of rabbits, spirals on a pine cone). OE, P

•  Prepare a graphic organizer (web) of your family. In a cooperative group, each student assumes the role of a specified family member. Each student explains his/her relationship to other members of the group. OE, P

•  Stand in hula hoops (Venn diagram) according to assigned attributes, (e.g., red shirts in one hula hoop, blue tennis shoes in another hoop). PE

Sample Middle School Activities   

 

•  Use models to compare the relative sizes of fractions and decimals (fraction bars, decimal factory, and/or decimal squares). OE

•  Analyze problems to see how the field properties can simplify computations and practice using mental math strategies (e.g., 12(1/2 + 1/3) = 12x1/2 + 12x 1/3 or 16+(84+59) = (16+84) + 59). OE
