How to Implement the New Math Standards,
Part III
by Arlyne LeSchack
Helping
all students become proficient in mathematics is the goal
for every school. In this article, I will review the content
strands as well as the bands within the content strand, and
the performance indicators (i.e., exactly what each student
should be able to do) within each strand. 

The
first content strand is Number Sense and Operations.
The bands within that content strand are: Number Systems, Number
Theory, Operations and Estimation.
Performance
standards:
 Students
will be able to understand numbers multiple ways of representing
numbers, relationships among numbers and number systems
 Students
will be able to understand the meanings of operations and procedures
and how they relate to one another.
 Students
will be able to compute accurately and make reasonable estimates.
The
second content strand is the alegbra strand. The bands
within that strand are variables and expressions, equations and
inequalities, patterns, relationships and functions, coordinate
geometry and trigonometric functions.
Performance
standards:
 Students
will be able to represent and analyze algebraically a wide variety
of problems solving situations
 Students
will be able to perform algebraic procedures accurately and
recognize, use and represent algebraically patterns, relations
and functions.
The
third content strand is the geometry strand. The bands
within this content strand are shapes, geometric relationships,
transformational geometry, coordinate geometry, constructions,
locus, informal proofs and formal proofs.
Performance
standards:
 Students
will use visualization and spatial reasoning to analyze characteristics
and properties of geometric shapes
 Students
will identify and justify geometric relationships formally and
informally
 Sstudents
will apply transformations and symmetry to analyze problem solving
situations,
students will apply coordinate geometry to analyze problem solving
situations
The
fourth content strand is measurement. The bands within
that strand are units of measurement, tools and methods, units,
error and magnitude and estimation.
Performance
standards:
 Students
will determine what can be measured and how using appropriate
methods and formulas
 Students
will use units to give meaning to measurements
 Students
will understand that all measurement contains error and be able
to determine its significance and develop strategies for estimating
measurements.
The
fifth content strand is statistics and probability. The
bands within the strand are the collection of data, the organization
and display of data, the analysis of data, making predictions
from data and probability.
Performance
standards:
 Students
will be able to collect, organize, display and analyze data
 Students
will be able to make predictions that are based on data analysis
 Students
will understand and apply the concepts of probability
In the final article of this series I will discuss the performance
standards for the five process strands.
