scale project each year, beginning in fourth grade, drawn from the
following kinds and, over the course of elementary school, conducts
projects drawn from at least two of the kinds.
A single project may draw on more than one kind.

a
Data study, in which the student:

decides on a group or groups to be sampled and makes predictions
of the results, with specific percents, fractions, or numbers; 
• 
collects, represents, and displays data in order to help make the
decision or recommendation; compares the results with the predictions;

writes a report that includes recommendations supported by diagrams,
charts, and graphs, and acknowledges assistance received from parents,
peers, and teachers. 
b
Science study, in which the student:

results with predictions;

the results with diagrams, charts, and graphs; acknowledges assistance

peers, and teachers. 
The student conducts at least one large
scale investigation or project each year drawn from the following
kinds and, over the course of middle school, conducts investigations
or projects drawn from three of the kinds.
A single investigation or project may draw on more than one kind.

a
Data study based on civic, economic, or social
issues, in which the student: 
• 
selects an issue to investigate; 
• 
makes a hypothesis on an expected finding, if appropriate; 
• 
gathers data; 
• 
analyzes the data using concepts from Standard 4, e.g., considering
mean and median, and the frequency and distribution of the data; 
• 
shows how the study’s results compare with the hypothesis; 
• 
uses pertinent statistics to summarize; 
• 
prepares a presentation or report that includes the question investigated,
a detailed description of how the project was carried out, and an
explanation of the findings. 
b
Mathematical model of physical phenomena,
often used in science studies, in which the student: 
• 
carries out a study of a physical system using a mathematical representation
of the structure; 
• 
uses understanding from Standard 3, particularly with respect to
the determination of the function governing behavior in the model; 
• 
generalizes about the structure with a rule, i.e., a function, that
clearly applies to the phenomenon and goes beyond statistical analysis
of a pattern of numbers generated by the situation; 
• 
prepares a presentation or report that includes the question investigated,
a detailed description of how the project was carried out, and an
explanation of the findings. 
c
Design of a physical structure, in which
the student: 
• 
generates a plan to build something of value, not necessarily monetary
value; 
• 
uses mathematics from Standard 2 to make the design realistic or
appropriate, e.g., areas and volumes in general and of specific geometric
shapes; 
• 
summarizes the important features of the structure; 
• 
prepares a presentation or report that includes the question investigated,
a detailed description of how the project was carried out, and an
explanation of the findings. 
d
Management and planning, in which the
student: 
• 
determines the needs of the event to be managed or planned, e.g.,
cost, supply, scheduling; 
• 
notes any constraints that will affect the plan; 
• 
determines a plan; 
• 
uses concepts from any of Standards 1 to 4, depending on the nature
of the project; 
• 
considers the possibility of a more efficient solution; 
• 
prepares a presentation or report that includes the question investigated,
a detailed description of how the project was carried out, and an
explanation of the plan. 
e
Pure mathematics investigation, in which
the student: 
• 
extends or “plays with,” as with mathematical puzzles,
some mathematical feature, e.g., properties and patterns in numbers; 
• 
uses concepts from any of Standards 1 to 4, e.g., an investigation
of Pascal’s triangle would have roots in Standard 1 but could
tie in concepts from geometry, algebra, and probability; investigations
of derivations of geometric formulas would be rooted in Standard 2
but could require algebra; 
• 
determines and expresses generalizations from patterns; 
• 
makes conjectures on apparent properties and argues, short of formal
proof, why they seem true; 
• 
prepares a presentation or report that includes the question investigated,
a detailed description of how the project was carried out, and an
explanation of the findings. 
The student conducts at least one large
scale investigation or project each year drawn from the following
kinds and, over the course of high school, conducts investigations
or projects drawn from at least three of the kinds.
A single investigation or project may draw on more than one kind.

• 
carries out a study of data relevant to current civic,
economic, scientific, health, or social issues; 
• 
uses methods of statistical inference to generalize from the data; 
•

or phenomenon, in which the student: 
• 
carries out a study of a physical system or phenomenon by constructing
a mathematical model based on functions to make generalizations about
the structure of the system; 
• 
uses structural analysis (a direct analysis of the structure of
the system) rather than numerical or statistical analysis (an analysis

organizational plan, and conclusions, and uses an appropriate balance
of different ways of presenting information.

issues such as optimization, costbenefit projections, and risks; 
• 
uses decision rules and strategies both to analyze options and balance
tradeoffs; and brings in mathematical ideas that serve to generalize
